how do u find the points of a vertical line

Question

I have this linear equation project due and I don’t know how to find the point on a vertical line

Answer 1

When you have a straight vertical line, the slope is essentially infinite. Instead of the standard slope-intercept formula where you're solving for y, you're answering for x instead (because EVERY y is possible). Instead of:

y = mx + b, you have:

x = C, where C is the constant.

 

Here are some examples by using points to help you visualize:

(0, 5) (15, 5), (80, 5) (675421091, 5)  (-64, 5) (-64913, 5)

 

No matter what you put in for the y value, the x is always going to be the same. (Or if you want to think of solving for y, y equals any and every possible number, but x never changes.)
