Activity Sheet 2–8
Calculating Slope and Equations
This activity provides practice using the 4–4 slope tool to find the slope of lines. Once the slope
is found a linear equation can be calculated.
Directions: Work alone or with a partner. Each member must submit this sheet with all
measurements properly labeled. Your task is to use the 4–4 slope tool to directly calculate the
slope. Then find the equation of the line produced by each question. Write the equation in
Standard form, Slope Intercept Form and Point Slope form.
