Step-by-step explanation
the function for the distance is given by

then, let
speed= 0.25 m/s
time= t
distance= 2m
hence, replace

Step 2
now, to graph the line we need 2 points
a) when t= 0

P1(0,0)
b) when the car has covered 2m
let d=2
replace and solve for x

P2(8,2)
finally, draw a line that passes through the point P1(0,0) and P2(8,2)
I hope this helps you
