Answer:
A
Step-by-step explanation:
I think that's the answer because
60 minutes = 1 hr
120 minutes = 2hrs
So the graph must be constant with the write amount of min/hr since the x axis is the number of mins and the y axis is the number of hours. (x,y)
(60,1)
(120,2)
(2x-5y)+(x+y)=(2x+x)+(-5y+y)=3x-4y.
therefore:
(2x-5y)+(x+y)=3x-4y
14.4 inches / 9 = 1.6 inches
Each column is 1.6 in wide
