Question

what is the x-intercept and y-intercept of the graph of 2x - 4y = 8

Answer 1

To find the y-intercept make x = 0.
To find the x-intercept make y = 0.

Answer 2

2*0 - 4*0 = 8

Answer 3

To find y-intercept make x = 0. So:
2x - 4y = 8
2(0) - 4y = 8

Solve. What is y?

To find x-intercept make y = 0. So:
2x - 4y = 8
2x - 4(0) = 8

Solve. What is x?

Answer 4

Is that easier to understand?

Answer 5

y = -2

Answer 6

x = 4

Answer 7

x-intercept is (4,0) and y-intercept is (0,-2)

Answer 8

Right! :D

Answer 9

yaay :)
