On the $xy$-plane above a line contains the points $(0,4)$ and $(2,0)$. What is the point-slope form of the equation for this line?

\[ \left ( y - \answer {4} \right ) = \answer {-2} (x - 0) \]

On the $kt$-plane above, a line contains the points $(-1,3)$ and $(2,5)$. What is the point-slope form of the equation for this line?

\[ \left ( t - \answer {5} \right ) = \answer {-2} (k - 2) \]

On the $Wf$-plane above, a line contains the points $(-2,6)$ and $(3,-7)$. What is the point-slope form of the equation for this line?

\[ \left ( f - \answer {-7} \right ) = \answer {-\frac {13}{5}} (W - 3) \]
