Question

Given m = -1/5 and the point (1, 2), which of the following is the point-slope form of the equation?

y - 2 = -1/5(x - 1)

y + 1 = -1/5(x + 1)

y + 2 = -1/5(x + 1)

y + 2 = 1/5(x - 1)

Answer 1

y - 2 = -1/5(x - 1).

Explanation:

y - y1 = m(x - x1) is the general form .

Here x1 = 1, y1 = 2 and m = -1/5, so it is:

y - 2 = -1/5(x - 1).
