Answer:
Step-by-step explanation:
<u>Using slope formula to find the value of k:</u>
- (-9 - k)/(-2 - (-4)) = - 9
- (-9 - k)/2 = - 9
- - 9 - k = - 18
- k = 18 - 9
- k = 9
Answer:
y=-3.5x^2+9.5x-4
Step-by-step explanation:
y=a*x^2+b*x+c
4=0+0+c => c=-4
2=a+b-4 =>a+b=6
1=4a+2b-4 => 4a+2b=5
2a+b=2.5
a+b=6
a=-3.5
b=9.5
It’s actually 11.
Hope that helps!
B should be the answer :)
