\begin{shortquiz}[answer] Answer each of the following. Passing is 100\%.

\begin{questions}

\item Find the equation of the line that passes through the two
points $P(1,1)$ and $Q(2,5)$.

\rp\RespBoxMath{y = 4 * x - 3}(xy){4}{.0001}{[0,1]x[0,1]}*{ProcRespEq}\hfill
    \CorrAnsButton{y = 4 * x - 3}\kern1bp\sqTallyBox

\item Write the equation of the circle centered at the point $C(1, -1)$ with radius $4$.

\rp\RespBoxMath{(x-1)^2 + (y+1)^2 = 16}(xy){4}{.0001}{[0,1]x[0,1]}*{ProcRespEq}\hfill
    \CorrAnsButton{(x-1)^2 + (y+1)^2 = 16}\kern1bp\sqTallyBox

\item Consider the function $f(x,y) = 2x^2y - 3xy^3$. Find the equation of the
line tangent to the surface of the graph of this function at the point on the
graph corresponding to $(x,y) = (-1,-1)$.

\rp\RespBoxMath{z+5 = 7*(x+1)+11*(y+1)}(xyz){4}{.0001}{[0,1]x[0,1]x[0,1]}*{ProcRespEq}\hfill
    \CorrAnsButton{z+5=7*(x+1)+11*(y+1) or z=7*x+11*y+13}\kern1bp\sqTallyBox
