Answer:

d = 25t

Step-by-step explanation:

pick tow points on the line, the easier for me is (0,0) and (2,50).  The equation options are given in slope intercept form such as y = mx + b; where m is the slope and be is where the line intercepts the y-axis.  We can see that "b" is zero because the line intercepts the y-axis at 0 (b = 0).

to find the slope you use the two points for the m

m = [tex]\frac{(y2 - y1)}{(x2 - x1)}[/tex]  = [tex]\frac{(50 - 0)}{(2 - 0)}[/tex]  = 25 is the slope

Therefore the equation should d = 25t
