isaiah has $80 to order shirts for some of his family members. the linear equation y = -10x + 80 represents the amount of money remaining, y, after isaiah orders x shirts. graph the equation.

isaiah has $80 to order shirts for some of his family members. the linear equation y = -10x + 80 represents the amount of money remaining, y, after isaiah orders x shirts. graph the equation.

Answer

Explanation:

Step1: Find the y - intercept

The equation is in slope - intercept form (y = mx + b), where (b) is the y - intercept. For (y=-10x + 80), when (x = 0), (y=80). So one point is ((0,80)).

Step2: Find the x - intercept

Set (y = 0) and solve for (x). (0=-10x + 80) (10x=80) (x = 8). So another point is ((8,0)).

Step3: Plot the points and draw the line

Plot the points ((0,80)) and ((8,0)) on the coordinate plane. Then draw a straight line passing through these two points.

Answer:

Plot the points ((0,80)) and ((8,0)) and draw a line through them.
