Question

Find the equation of the line that goes through the points (-15, 3) and (-15, -7).

Answer 1

Answer: x = -15

Step-by-step explanation: This is because when you use the gradient formula (y2-y1/x2-x1) you get -10/0 which means it's 'undefined' and undefined slopes are vertical so x = -15. Hope this helps ✌️

Answer 2

The linear equation that passes through the two given points is x = -15

How to find the equation of the line that goes through the points (-15, 3) and (-15, -7)?

This is kinda trivial, we can see that both points have the same x-value.

So we will have a vertical line, because if we have two points with the same x-value, then we must have a constant line of the form:

x = a

And the value of a is the x-value of the points, so the linear equation here is:

x = -15
