The answer is D because
60 times 5=300
20 times 8=160

Answer:
2/5 or .4
Step-by-step explanation:
basically look at the points where the line meets the graph. two points would be 0,20 and 50,40. then count the amount that it changes vertically and then horizontally. +20vertical +50 horizonal giving the slope 20/50. this can then be simplified to 2/5 or the equivalent number .4
No actually you can just multiply both sides of the equation by 2 and get y-4=20. then add 4 to both sides to get y=24.
