Answer: y=3x-2
So to find the y-intercept, you look to see where the point is located when it crosses the y-axis. In this case, it crosses at (0, -2).
To find the slope, you do rise/run. Pick one point to start with. Count upwards, then over. You could also use slope formula if you know two points on the graph: slope= (y2-y1) / (x2-x1)
