The population of a city increases by 4,00 people each year. In 2025, the population is projected to be 450,000 people. What is an equation that gives the city population p (in thousands of people) x years after 2010?

Question

The population of a city increases by 4,00 people each year. In 2025, the population is projected to be 450,000 people. What is an equation that gives  the city population p (in thousands of people) x years after 2010?

A)p=4x+50
B)p-450=4(x-15)
C)p-15=4(x-450)
D) p=4x+15************

clearly not D. Using that, p(15) = 60+16 = 75, when the projection states it will be 450 We have a slope (4) and a point (15,450). So, using the point-slope form, we get p-450 = 4(x-15)
