This is similar to Problem 5 from your Section 2.3 worksheet.

For each description, select the equation in point-slope form that defines such a line.

a) The line through $(11,14)$ with a $m=0$.
$x=11$
$x=14$
$y=11$
$y=14$

b) The line through $(7,-13)$ with an undefined slope.
$x=7$
$x=-13$
$y=7$
$y=-13$
