Answer:
A (0,3)
Explanation:
the equation is Slope Intercept form where 1/2 is your slope and 3 Is your y intercept you can see that a is the correct answer because y intercept will also have 0 as an x and a has 0 as x and 3 as y so that is your slope intercept so it is a ordered pair on the line.
Hope this helped let me know if you want a better explanation :)
