Anytime we need to get the equation of a line, we need 2 things:
a point a slopeSo, what do we do if we are just given 2 points and no slope?No problem -- we'll just use the 2 points to pop the slope using this guy:
Check it out:
Let's find the equation of the line that passes through the points
(1,1/2) and (-1,-1)
This one's a 2-stepper...
STEP 1: Find the slope
STEP 2: Now, use the point-slope formula with one of our points,
