LINEAR EQUATION An equation of the form A x B y = C, where A and B are not both zero, is called a linear equation in two variables Here is an example of a linear equation in two variables, x and y The equation y = − 3 x 5 is also a linear equation But it does not appear to be in the form A x B y = CGraphing Linear Equations using X/Y Tables Part 1 Tell whether the ordered pair is a solution of the equation Just substitute the given x and y to see if the equation "works" Write "solution" if it works and "not a solution" if it doesn't
Let x = k, then y = 5 k So, the ordered pair (k, 5 k), where k is a constant, will be the solution of the given pair of linear equations Thus, the pair of linear equations is inconsistent Thus, the pair of linear equations is consistentSTEP 1 Draw a table of values for the x and y coordinates Add the x coordinates 0, 1, 2, 3 and 4 3 of 8 STEP 2 Using the equation y = 2x 1, calculate the value of y by using the x value inIs called a linear equation in two variables
Complete a table of values by determining x and y values Then the line is graphed on the coordinate planehttp//mathispower4ucomLinear equations represent direct proportional relationships between x and y A table of values contains the exact values of x and y In this section, we will learn how to draw graphs based on the data from tables of values From the tables and graphs, we will try to describe and determine whether the relationships are linear or notOne way is to choose a value for x x and then solve the equation for y y Or, choose a value for y y and then solve for x x We'll start by looking at the solutions to the equation y = 5x−1 y = 5 x − 1 we found in the previous chapter We can summarize this information in a table of solutions

4 Write an equation for the table above Make sure your answer is in y=mxb form, and don't leave any spaces!(2, 10 4) = 2;Since, as we just wrote, every linear equation is a relationship of x and y values, we can create a table of values for any line These are just the x and y values that are true for the given line In other words, a table of values is simply some of the points that are on the line Example 1
Graphing Linear Equations using X/Y Tables Part 1 Tell whether the ordered pair is a solution of the equation Just substitute the given x and y to see if the equation "works" Write "solution" if it works and "not a solution" if it doesn't 1) y=4x2;For example, if the slope is 5 and the yintercept is 7, you should write y=5x7 x 4 Subtract the xcoefficient A from the y solution To make the equation remain balanced, when you add to the x term, you must then subtract from the y term For this problem, beginning with the solution y=102, subtract the x coefficient of 87, as follows y = − 102 − 87 = − 1 {\displaystyle y==1}
Graphing a Linear Equation Make A TABLE Example 2 Steps Example Step 1 Make a tchart Step 2 Pick in 35 values for x *Use (2, 0, 2) to start unless it is a real life problem * If slope is a fraction use the & – denominator and 0 Step 3 Substitute each value for x and y = solve for yStep 1 Notice that the change in cost is the same for each increase of 100 minutes So, the relationship is linear Step 2 Choose any two points in the form (x, y), from the table to find the slope For example, let us choose (100, 14) and (0, ) Use the slope formula m = (y2 y1) / (x2 x1) SubstituteLinear equations are equations of the first order These equations are defined for lines in the coordinate system An equation for a straight line is called a linear equation The general representation of the straightline equation is y=mxb, where m is the slope of the line and b is the yintercept Linear equations are those equations that are of the first order

How to Tell if a Table is Linear You can tell if a table is linear by looking at how X and Y change If, as X increases by 1, Y increases by a constant rate, then a table is linear You can find the constant rate by finding the first difference This table is linear the first difference between Y1 & Y2, Y2 & Y3, and Y3 & Y4 is 2Example 5 Find the equation of the line passing through (−4, −2) and (1, 3) Solution When finding a linear equation using slopeintercept form y=mxb y = m x b , the goal is to find m and then b Step 1 Find the slope m In this case, given two points, use the slope formula Substitute m=1 m2x 3y = 5 3y = 5 2x Table of solutions X –1 2 y –1 –3 We plot the points (–1, –1) and (1, –3) on a graph paper and join the same by a ruler to get the line which is the graph of the equation 2x 3y = –5 x y = –1 ⇒ y = – 1 – x Table of solutions X 0 1 y –1 –2 We plot the points (0, –1) and (1, –2) on the same graph paper and join the same by a ruler to

For the linear equation y = a bx, b = slope and a = y intercept From algebra recall that the slope is a number that describes the steepness of a line, and the y intercept is the y coordinate of the point (0, a) where the line crosses the y axis Three possible graphs of y = a bx (a) If b > 0, the line slopes upward to the right
