First, simplify the negative addition. 
Follow the order of operations by dividing first. 
Add and subtract from left to right. 
So -4 is where the line crosses the y axis (aka the y intercept). then to find other points, you can either count of the line by doing the slope (rise over run) in this scenario you would go up 8 and over 1 or you can plug in numbers for x and then can get ordered pairs for other points
