I believe it is y=mx+b..........y equals slope times x plus the y intercept...or y=-8/3x+4.that would mean your slope would be negative. meaning it would go from the left top hand corner and fall through to the bottom right hand corner.
First do 60-48 then that equals 12. Next do 12 divide by 6x and your answer is 2
