First, we need to know the slope-intercept equation which is: Y=mx+b.
Where b, equals the y-intercept. Here, the y-intercept is -4, which is where the line touches the y. Next, we have to figure out the "m" in the equation, which is the slope. To figure out the slope, you have to choose 2 points on the graph and see how many "Rise" and "Runs" you have to do to go from one point to another. In this case, the slope is 8/3. So, we have the formula of y= 8/3x+-4
