Question

Just when I thought I was okay...
I'm trying to figure out a way to find an equation that would work for all three plots on the graph.

Answer 1

use two points, and determine the slope of the line
\[m= \frac{y_2-y_1}{x_2-x_1}\]
once you have the slope
the substitute the slope and a point into the point slope equation

\[y-y_1=m(x-x_1)\]
then just simplify into either standard or slope intercept form

Answer 2

Ok, so the when I find the slope, while that also apply to the third point i didn't inc
lude?

Answer 3

this is assuming that the 3rd point is on the same line, if its not, then you'll have to find 3 different equations
