How do you write an equation of a line that passes through (-4, 3) with a slope that is undefined?

Nov 28, 2016

Please see the explanation for why the equation is: $x = - 4$

Explanation:

Undefined slope means vertical line. The equation of a vertical line is of the form:

$x = {x}_{0}$

where ${x}_{0}$ is the x coordinate of any point through which you want the line to pass. Therefore, a line with undefined slope that passes through $\left(- 4 , 3\right)$ is:

$x = - 4$
