Which of the following ordered pairs could represent the y-intercept of a function.

snow_lady [41]

<h3>Answer: (0,5)</h3>

This is because the x coordinate is 0. For any y intercept, the x coordinate is always 0 as this indicates the point is on the y axis.

Contrast this with something like (9,0) and we see that y = 0 indicating this point is an x intercept (it is on the x axis).
