Question

Which of the following ordered pairs are y-intercepts? Check all that apply

(4,0)
(-1, 1)
(0,0)
(0,-7)
(-2,-2)
(0,-0.25)​

Answer 1

A y-intercept is the value at which x = 0.

(4,0) is not a y-intercept because x = 4.

(-1, 1) is not a y-intercept because x = -1.

(0,0) is a y-intercept because x = 0.

(0, -7) is a y-intercept because x = 0.

(-2, 2) is not a y-intercept because x = -2.

(0, -0.25 is a y-intercept because x = 0.
