A. Find the slope of the line through points (-2,8) and (5,-1) (I’ve already solved this one, it’s -9/7.

B. Write the equation of a line through the two points in part A

C. What would be the slope of the line parallel to the line given in part a.

D. What would be the slope of the line perpendicular to the line given in part a.

y=20x

: )

hope this

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function

i believe your answer is a
