Suppose a city with population 900000 has been growing at a rate of 7% per year. If this rate continues, find the population of this city in 15 years.

1,971,000

Step-by-step explanation:

7% increase per year= 7/100 x 900,000

=63000; population will therefore increase by 63,000 per year.

In 17 years, it will have increased by 63,000 × 17 = 1,071,000

Population in 17 years will be current population + increase

=900,000+ 1,071,000

=1,971,000

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
