Given that the slope of line is undefined and the x intercept is -7

To find: Equation of line

If a line has undefined slope, then it is a vertical line

A vertical line has undefined slope because all points on the line have the same x-coordinate

<em><u>The equation of a vertical line always takes the form:</u></em>

x = b

<em><u>Thus the equation of line is:</u></em>

x = -7

Therefore, the equation of line is found
