The way you find slope is called Rise over run. The two points you use to find slope are (-2,0) and (0,4). Rise has to do with Y values so you take 4-0 which equals 4. Run is the X values so you would take 0-(-2) which equals 2. So rise over run is 4 over 2. The fraction 4/2 equals 2. so slope equals 2. Then the Y-intercept is what you add to the equation. The Y-intercept is positive 4. So the end equation equals y=2x+4
