Question

Use the situation and the data in the graph to create the table

Answer 1

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

$\begin{gathered} m=\frac{y2-y1}{x2-x1} \\ m=\frac{5-1}{1-0} \\ m=4 \end{gathered}$

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).
