Question

What is the equation of a line with a y-intercept at (0, 2) and a slope of 3?
A. y=2x+3 B. y=3x-2 C. y=3x+2 D. y=-2x+3

Answer 1

We are looking for a coefficient of 3 (the slope) on the x term. So we can eliminate A and D.
(0,2) means the y intercept is 2, because the x coord is zero (the y axis). The y intercept is the constant term, so C is the answer: y=3x+2.
