HEY What is SLOPE
The slope m of a line is determined by any two points on the line If given the coordinates 1 3 and 4 5 you can find the slope of the line that the two points are located on How you say Use the rise run

Using Rise over Run
The points again are 1 3 and 4 5 First find the slope of the line using the formula y y
m
2 1

x2 x1

To use this formula you must identify what x1 y1 x2 and y2 are

Using the formula
y2 y1
m

x2 x1

X1 1 y1 3 x2 4 y2 5 Now plug the numbers in
m

5 3 4 1



2 3

So this is your answer Rise and Run

Slope of Lines
There are different types of slopes In the previous example the slope of the line was positive Lets graph the two points and look at the direction of the line

All SLOPES

POSITIVE SLOPE

NEGATIVE SLOPE

ALL SLOPES CONTINUED

ZERO SLOPE

NO SLOPE OR UNDEFINDED
