1 Writing Equations from Tables Mrs. Kuznia Math 8 Day 54

2 Objective Given a table of x and y values, we can write an equation. We do this by looking for patterns!!

3 Example xy We need to use y= mx+b. We need to determine 2 pieces, the m and the b. How do we get the m? Look in the y colums for a pattern. This is the m. How do we get the b? Find the 0 in the x column, and match it with the y-value.

4 Continued xy

6 Example xy

7 Example xy

8 Use the table to graph the appropriate line. Then, give the equation of the line. xy
