Question

How do you write equation of a line in slope-intercept form that passes through the points ( -2, 5) and (-2, 11)?

Answer 1

See a solution process below:

Explanation:

Because the values for `x` in both points are the same we know this is a vertical line where for each and every value of `y`, `x` is equal to `-2`

By definition, the slope of a vertical line is undefined.

Therefore, we cannot write this equation in slope-intercept form.

The equation for this line is:

`x = -2`
