Question

A vehicle at the starting line travels at a constant speed of 0.5 miles per min. which function could describe this vehicle.

A.y=0.5
B.y=0.5x
C.y=x+0.5
D.y=0.5x+1

Answer 1

We have the equation y=mx+b. Here, m is multiplied by x and represents the slope in our line, or its speed. The b here represents the starting point. First, since we start at the starting line, b is 0 (since we start from 0). Next, since our speed is 0.5, we multiply x by 0.5 to get 0.5x=y
