Question

Given the equation y=2x-8, which statement is correct ? A.Y=2(x-4) has a y-intercept of 4 B. Y=2(x-4)has a y-intercept of -4 C. Y=2(x-4) has a x- intercept of 4 D. Y=2(x-4)has a x intercept of -4

Answer 1

Correct option: C -> Y=2(x-4) has a x- intercept of 4

Explanation:

To find the y-intercept of the equation y = 2x - 8, we just need to find the value of y when x = 0:

`y = 2*0 - 8 = -8`

To find the x-intercept of the equation y = 2x - 8, we just need to find the value of x when y = 0:

`0 = 2*x - 8`

`2x = 8`

`x = 4`

So the y-intercept is -8 and the x-intercept is 4.

Correct option: C -> Y=2(x-4) has a x- intercept of 4
