    \[\frac{ Y2-Y1 }{ X2-X1}\] Can you find two coordinates on the line? (x1,y1) and (x2,y2)

    So, 25 would be Y, and 3 would be x?

    Yeah that's one point! Another point is (0,0) right?

    Now use those two coordinates to find the rate of change using the formula above.

    Yeah, so \[\frac{ 25 - 0}{ 3 - 0 } = \frac{ 25 }{ 3}\]

    Fractions are generally more accurate than decimals, but it depends what your teacher is asking for. If in doubt, keep it as a fraction!
