Question

Select the equation of the line that passes through the point (–2, 1) and has slope 3 in point-slope form.


A.
(y – 1) = 3(x + 2)

B.
(x – 2) = 3(y + 1)

C.
(x + 2) = 3(y – 1)

D.
(y + 1) = 3(x – 2)

Answer 2

A cause the form of the slope is : k = (y-y_1)/(x-x_1), where (x_1,y_1) is the point. In this case x_1 = -2, y_1 = 1 so 3 = (y-1)/(x+2)
