2-22.

Find the equation for the line that passes through $(-1,-2)$ and $(4, 3)$. Is the point $(3, 1)$ on this line? Be sure to justify your answer.

Calculate the slope of the line through the $2$ given points by either creating a slope triangle, or by finding the change in $y$ over the change in $x$.
