Find an equation of the line containing the points (-5,7) and (-5,8). express your answer in slope intercept form.

Try, pls, this:
1. Note, that for the both points x₁=x₂=-5, it means line is vertical, that is equation form is x=a, where a=number.
2. The number for 'a' may be extracted from points, a=-5.
3. Equation for line is x=-5.
