Question

What is the x and y intercept of each equation?

Answer 1

To find the x-intercept you plug 0 in for y and solve for x

To find the y-intercept you plug 0 in for x and solve for y

20x + 8(0) = 240
20x = 240
x = 12

20(0) + 8y = 240
8y = 240
y = 30

For the first equation your x-intercept is (12,0) and your y-intercept is (0,30)


15x + 3(0) = 270
15x = 270
x = 18

15(0) + 3y = 270
3y = 270
y = 90

For the second equation your x-intercept is (18,0) and your y-intercept is (0,90)

Answer 2

The "x" intercept is where a line would mark across the "x" axis. 

The "y" intercept is where a line would mark across the "y" axis. 

X is horizontal and Y is vertical.
