Question 143114: Find the slope, if it exists of the line containing the pair of points
(2, 5) and (3, -9)
The slope m = ?
Will someone please help me with this I do not understand. Answer by Earlsdon(6294) (Show Source):
You can put this solution on YOUR website! That's an interesting caveat - "...if it exists..."
All lines will have a slope, either positive, negative, zero, or undefined!
Let's see what your slope is.
Where: and are taken from the first point (2, 5), and... and are taken from the second point (3, -9)
Making the appropriate substitutions, we get: Simplify.
Because the slope is negative, the line through the two given points leans to the left.
Here's a graph of the line:
