Write an equation that has an undefined slope
Think of it using the hill analogy again.
Well you know that having a 0 in the denominator is a big no, no. As shown above, whenever you have a vertical line your slope is undefined. The x-values can be any number, but y must always be 1.
We can get down to business and answer our question of what are the slope and y-intercept. And that's a no-no. What does this form if we graph it?
Slope is defined as the rise over the run, right? All horizontal lines have slope 0. Because we can't divide by zero!
How to write an equation with an undefined slope and a point
Thank you! All these are on the line. As I walk along it, it doesn't rise very fast over distance. But I'll try to explain. This means the slope is undefined. So all the points on this line will have 1 as their y coordinate. Why is this so? So, for all our efforts on this problem, we find that the slope is undefined and the y-intercept does not exist. That is, the rise is 1, and the run is 0. Now I have 2 points so I can draw my line between them. Think of it using the hill analogy again.
