Question

What is the point-slope form of a line with slope 3 that contains the points (2,1)

Answer 1

y - 1 = 3(x - 2)

Explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

here m = 3 and (a, b) = (2, 1), hence

y - 1 = 3(x - 2) ← in point- slope form
