Answer: A
Explanation:
A y-intercept is a point where a function (i.e a line) intercepts the y-axis.
Every point on the y-axis has a x value of 0.
The ordered pair will look like this (0,y)
In answer a, you have an x value of 0 with a corresponding y value of 3.
This point is (0,3).
You could also graph the points and look for where the function crosses the y-axis.
