Question

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

Answer 1

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 `(-4, 3)` is:

`x = -4`
