What is the equation of a line with slope 4 that passes through the point (1,2)?

(A) y – 1 = 4(x – 2)

(B) y – 2 = 4(x – 1)

(C) y + 1 = 4(x + 2)

(D) y + 2 = 4(x + 1)

The point-slope form of an equation is y - .

The slope, m, is 4, is 1, and is 2.

y – 2 = 4(x – 1)

(B) is the correct equation.
