The current population of a small city is 29000 people. Due to a loss of jobs, the population is decreasing by an average of 375 people per year. How many years (from now) will it take for the population to decrease to 26000 people? write an equation.
***
Equation takes the form: y=mx+b, m=slope, b=y-intercept
For given problem:
slope=-375
y-intercept=29000 (population now, 0 years
x=years from now
equation: y=-375x+29000
26000=-375x+29000
375x=3000
x=8
How many years (from now) will it take for the population to decrease to 26000 people? 8
