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
|
|
a slope |
ALWAYS!
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
