RESTAURANTS In 2012, a popular pizza franchise had 2483 restaurants. In 2017, there were 2606 franchised
lisabon 2012 [21]

y  -  2483  =  24.6(x - 2)

Let x represent the number of years after 2010

Let y represents the number of restaurants in x years

2012 is 2 years after 2010

2017 is 7 years after 2010

Number of restaurants owned by RESTAURANTS in 2012 = 2483

This can be represented in coordinate form as (2, 2483)

Number of restaurants owned by RESTAURANTS in 2017 = 2606

This can be represented in coordinate form as (7, 2606)

The equation of a line in point-slope form is:

y-y_{1} = m(x - x_{1}  )

where m represents this slope, and is calculated as:

m = \frac{y_{2} - y_{1} }{x_2-x_1} \\m = \frac{2606-2483}{7-2} \\m = \frac{123}{5} \\m = 24.6

Substitute x₁ = 2, y₁  = 2483, and m = 24.6 into the point-slope equation

The equation in point-slope form becomes:

y  -  2483  =  24.6(x - 2)
