Given
Graph and cubes
Procedure
a. Use the situation and the data in the graph to create a table
Table
_________________
x = number of block ! y = number of squares painted
_________________
1 ! 5
2 ! 9
3 ! 13
b. What is the y-intercept
(0, 1)
c. What is the slope

The slope would be 4
d. Explain how you find the slope
Pick two points on the line and determine their coordinates. Determine the difference in y-coordinates of these two points (rise). Determine the difference in x-coordinates for these two points (run). Divide the difference in y-coordinates by the difference in x-coordinates (rise/run or slope).
