Question

Given m = -1 and the point (1, 2), which of the following is the point-slope form of the equation?


a y + 2 = -2(x - 1)


b. y + 2 = -(x + 1)


c. y - 2 = -(x - 1)


d. y + 2 = -(x - 1)

Answer 1

It's C).
is you add 2 to both sides it gives you your Y value shown previously. Then, distribution of the parenthesis so you get -x (m= -1) and you get positive one ((1),2) the one in your brackets previously.
