In the last lesson, I showed you how to get the equation of a line given a point and a slope using the formula
Anytime we need to get the equation of a line, we need two things
|? a point?||
So, what do we do if we are just given two points and no slope?
No problem -- we'll just use the two points to pop the slope using this guy:
Check it out:
Let's find the equation of the line that passes through the points
This one's a two-stepper...
STEP 1:? Find the slope
