Slope:y2-y1/x2-x1
-1-4/4-(-3)
-5/4+3
-5/7
Answer:
h=A/(b1+b2/2)
Step-by-step explanation:
it is the reverse
1. vertex is -4 because:
x^2-8x-20,
a=1, b=-8 , c=-20
use vertex form! -b/2a = -8/2(1) = -8/2 = -4.
2. axis of symmatry is the x which is also -4. The same steps go for the second one.
3. y intercept, I think the answer is -20. Im not sure for this one.
