Lines with an "undefined" slope are in the form of x = (some number). Examples: x = 3, x = 7, x = 100 etc.
In this case, you are given a point that the line goes through. Notice that the x-value of the point (-3, 4) is -3. So x = -3 would be the equation of the line.

Slope-intercept form can not be uses for a line with "undefined" slope. Thus, x = -3, the Standard Form, must be used.11/15/22
