x= time in minutes, since time is independent.. y= miles is dependent, since you need time to move for your motorcycle to move.
Use the following formulas to write the equation of the line.
y=kx general equation of line and k= y / x to find the slope of the line
plug in 10 and 8 in their respective spots in the second formula and simplify to find the slope of the line.
k= 10/8....k= 5/4.. plug slope into first equation.
y= (5/4)x will track the distance of the motorcycle after any time as passed.
