Grade 9 - Slope without graphing

Using the change in the rise over the change in the run we can obtain the slope.
m=y2-y1/x2-x1

You use the coordinates of any two points on a line to determine your x and y values.
pg. 135-138 #(3,4 do not graph), 6, 7, (14,15 do not graph)

The questions get tougher as you continue but just think about how much is the line rising or running to figure out the missing values.
