Question

A tile pattern has 5 tiles in figure 0 and adds 7 tiles in each new figure. write the equation of the line that represents the growth of this pattern.

Answer 1

For x 1= 0, y 1= 5, x 2 = 1 , y 2 = 5 + 7 = 12, ...
The equation in the slope-intercept form:
y = m x + b
b = 5, m = 7
Answer:
y = 7 x + 5
