Please use "^" to denote exponentiation: f(x) = x^2 - 6x.
To find f(-a), replace "x" with "(-a)" in the function (x) = x^2 - 6x:
f(-a) = (-a)^2 - 6(-a) = a^2 + 6a (answer)

<span>Perpendicular lines' slopes are reciprocals of one another. So we know the perpendicular line will have a slope of 1/2. Then we can use our points to find the rest.

8=0.5+b
7.5=b
y=2x+b</span>
