Select the 2 strategies for calculating slope.

• drawing a slope triangle

• creating a ratio table

• using the distributive property 

• setting up and solving a proportion

CCSS.HSF.LE.A.2

If you use the triangle method to solve for slope, what question do you have to ask yourself after?

• Does this line go in the positive or negative direction?

• Are the ratios proportional to each other?

Tags

CCSS.8.EE.B.5

What do both slope strategies use?

• dividing change in y by change in x

• dividing change in x by change in y

Tags

CCSS.8.EE.B.5

What does slope tell us about a line?

• Where it touches the y-axis

• The direction it goes in, its steepness
