Question

Determine the equation of the line given by the graph.

Answer 1

B, y=3x-2. It’s a positive line, so it can’t be C. The line intersects the y axis at -2 so we know it’s either B or D. If you count the points the line runs through, you can see it rises 3 points and only runs 1. That means the slope is 3/1 which equals 3. B’s slope is 3, so you have your answer!
