Question

A line has a slope of 7 and contains the point (5, −9).

Which equations represent the line?

Choose all answers that are correct.

A.
−7x + y = −44

B.
7x – y = 44

C.
(y − 9) = 7(x + 5)

D.
(y + 9) = 7(x − 5)

Answer 1

using the point slope form you'll have:
(y-y1) = m(x-x1)
y - (-9) = 7(x -5)
y + 9 = 7(x - 5)
or
y + 9 = 7x - 35
7x - y = 9 + 35
7x - y = 44

Answer 2

or multiplying the whole equation with -1
7x - y = 44
-7x + y = -44
