The equation of a function is y=2x−6 . If this function were graphed, what would its y -intercept be?

Question

A. 6

B. −3

C. −6

D. 2

Answer 1

To find the y-intercept of a function, you set x=0 and solve for y.

Given the function y=2x-6, setting x=0 we get:
y = 2(0) - 6
y = 0 - 6
y = -6

Therefore, the y-intercept of the function y=2x-6 is -6.

C. -6
