We will choose one point of the graph
(5,246.87)
We substitute the value of x=5 and if the equation is the one that matches we will obtain the values of y=250
A. y = 75x + 350
y=75(5)+350
y=725
This equation not matched
B. y = 34.375x + 75
y=34.375(5)+75
y=246.875
this equation matched
C. y = 8x - 75
y=8(5)-75
y=-35
This equation not matched
The equation that matches is the B. option
