Answer:
None of it.
Explanation:
Notice the slope is 2.75 this means for EVERY X the graph goes up by 2.75 in the Y axis. For example.
If at X=1 y=0
Then for X=2 y=2.75
and for X=3 y=2.75+2.75=5.5
also the graph must pass thought point (0,0), the origin, and none of the graph follow this.
You can also compare the slopes of each equations
for graph A, from x=1 to x=2 the height Y goes from 3 to 3.5, this is a slope of 0.5 (not the 2.75 we are looking for)
for graph A, from x=1 to x=2 the height Y goes from 1 to 2.5, this is a slope of 1.5 (not the 2.75 we are looking for)
for graph A, from x=1 to x=2 the height Y goes from 1 to 2.75 this is a slope of 1.75 (not the 2.75 we are looking for)
notice the last is similar to equation y=1.75X+b, just in case.
