Question

Which equation represents a line that has the slope 1/3 and passes through the point (-2,1)

Answer 1

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

Explanation:

Here m = 1/3 and (-2, 1) is a point on the line. The appropriate equation is

y - k = m(x - h), where (h, k) is the pt on the line.

Subbing the known values, we get:

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