Slope = (2+5)/(-3-1) = 7/-4 = -7/4
answer is B -7/4
The veretx is normally the minimum value
hack:
for f(x)=ax²+bx+c
the x value of the vertex is -b/2a
so
f(x)=1x²-16x+71
x value is -(-16)/(2*1)=16/2=8
find f(8) to find y value of vertex
f(8)=8²-16(8)+71
f(8)=64-128+71
f(8)=7
the vertex is (8,7)
the minimum value is 7
The answer would be 4 x 4 = 16+14= 30
Answer:
y = 1x + 46
