Question

which equation is the equation of the line, in point-slope form, that has a slope of -4 and passes through the point (7,1)

Answer choices:

A. y-7 = 4(x-1)

B. y-1 = -4(x+7)

C. y-1 = -4(x-7)

D. y-7 = -4(x-1)

    y – y1 = m(x – x1)

    First, you have to find m, or the slope.

    This is

    y – y

    ——-

    x – x

    It doesn’t matter which way you put it in, but I’m going to do it like this:

    -10 – (-8)

    ————-

    -7 – (-6)

    This reduces into:

    -2/-1 = 2

    Now, it’ll look like this (according to your answer choices, but you can use the other coordinate, also):

    y – (-10) = 2(x – (-7))

    This turns into:

    y + 10 = 2(x + 7)

    This answer is: C.
