Question

The slope of a line is undefined, and the x-intercept is -7. what is the equation of the line?​

Answer 1

The equation of line with undefined slope and x - intercept -7 is x = -7

Solution:

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

The equation of a vertical line always takes the form:

x = b

where, "b" is the x - intercept

Given x - intercept is -7

Thus the equation of line is:

$x = -7$

Therefore, the equation of line is found
