what is the equation of the line that passes through the points (6,4) and (6,-11)?

Question

 I'm stuck on a math problem and I really need help

Answer 1

At times you get solution by visualizing the line. Note that both points have x coordinate as 6. So the line through these is VERTICAL ( slope need not be computed as undefined ). As it is located 6 units from Y axis , its equation is x=6

Answer 2

m = y₂ - y₁

        x₂ - x₁

m = -11 - 4 = -15/0

         6 - 6

Division by zero is undefined. Lines with an undefined slope are vertical lines.

So, x = 6
