Question

Richmond High School has 1900 students and is shrinking by 15 students per year. Write a rule that represents the population at Richmond High School. Let x represent years and y represent population.

Answer 1

y = -15x + 1900

Explanation:

This is correct because, your base number is 1500, so that is your y-intercept. The school's population is shrinking by 15 students per year so, that becomes your slope. Hope I helped. ;)
