Question

Which equation represents a line that passes through (2, –0.5) and has a slope of 3?

Answer 1

y + 0.5 = 3(x - 2).

Explanation:

We use the point-slope form of the equation which is y - y1 = m(x - x1).

Here m = 3 , x1 = 2 and y1 = -0.5, so the equation is:

y - (-0.5) = 3(x - 2)

y + 0.5 = 3(x - 2).
