Answer:
The equation is:
y = 7x + 5
Explanation:
Given
Figure 0 = 5 tiles
Figure 1 = 5+7 = 12 tiles
Given that it adds 7 titles in each figure. Thus, the rate of change = 7 tiles
Thus, the equation is:
y = 7x + 5
Here
- 7 is the rate change or slope of the equation.
VERIFICATION:
setting x = 0 to determine the tiles in figure 0
y = 7x + 5
y = 7(0) + 5
y = 5
Thus, the figure 0 has 5 tiles
setting x = 1 to determine the tiles in figure 1
y = 7x + 5
y = 7(1) + 5
y = 7 + 5
y = 12
Thus, the figure 0 has 12 tiles (5 plus 7 added)
