Question

What is the equation in point slope form of the line that passes through the point (1, −2) and has a slope of 3?

Answer 1

y + 2 = 3(x - 1).

Explanation:

Using the point-slope form of a line:

y - y1 = m(x - x1)

Here m = 3 and (x1, y1) = (1, -2) so we have the equation:

y - (-2) = 3(x - 1)

y + 2 = 3(x - 1).
