Intro to Slope

We can find the slope when given a graph by selecting one point and counting how many spaces up or down (rise/vertical) and then how may spaces left or right (run/horizontal) until we reach the second point. 

Count from left to right like you read a book!

Finding the Slope of a Line

• Slope can tell us how steep a line is!

• Each line can be assigned a value (a #) that tells us how steep the line is.

• Slope is written as a ratio (rise/run)

• Always make sure to simplify your answer!
