Answer:
k > -9
Step-by-step explanation:
Subtract 12 from both sides as we want to isolate k-
30 - 12 = 18
-2k < 18
Divide both sides by -2
18/-2 = -9
k > -9
The general point-slope equation for a str. line is y-k = m(x-h),
where m is the slope and (h,k) is a point on the line.
Given that the line passes thru (-4,6) and (1,2), we find the slope as follows:
6-2
m = ----------- = -4/5
-4-1
Subst. -4/5 for m, 6 for k and -4 for h in y-k = m(x-h):
y-6 = (-4/5)(x+4)
Compare this result to the equations given.
Answer:
My answer is D) y = 2(x - 2.5)^2 + 6
