Answer:
6 because that is where the paarabola crosses the y line
Step-by-step explanation:
Y-intercept is what the y is when x is 0
(0,15) when x is 0, y is 15.
y-intercept is 15.
Roc: the x is going up by 4, the y is going up by 8
Always divide the difference for y by the difference for x
8 ÷ 4 is 2
ROC is 2
The answer is 4 and 6 (I mentioned the Z rule in my previous answer, I did not know the english term for it looks like it is 'alternate interior')
