Step-by-step explanation:
The y-intercept is the value where the line crosses the y-axis.
y-intercept of Line 1 (blue) = 4.
y-intercept of Line 2 (red) = 1.
Answer:
or 
Step-by-step explanation:

Add
on both sides.


Combine like terms;

Use the quadratic formula;
a=4
b=17
c=12




or 
Answer:
D. y =
Step-by-step explanation:
The solutions to this graph (meaning when y equals 0 or when the graph crosses the x-axis) are 4 and 5.
The only answer choice that has the solutions 4 and 5 when you factor it out is D.
Here's the proof:

Factors of 20: - 5 & -4
Sums that add up to -9: -5 + (-4)

(factor the first two terms and the last two terms separately)


(x - 5) (x - 4)
