Problem 12 - Entrance Test

What is the equation of the line that passes through point (2, 3) with slope -2 ?

Correct: A

The equation of a line with slope m passing through point (x1, y1) is y - y1 = m(x - x1). Given slope m = -2 and point (2, 3), we have y - 3 = -2(x - 2). Simplify: y - 3 = -2x + 4, y = -2x + 7.
