Slope Situations

Suppose a town has a population of 5,000 residents but that the population is decreasing by 200 people each year. Write a linear equation for this situation.

• y= -200x + 5000

• y= -5000x + 200

• y= 200x + 5000

• y= 5000x+ 200

A business purchases a computer for $1500. The computer goes down in value $200 each year when the new model is released. Write a function to model the situation.

• y= 1500x- 200

• y= 200x- 1500

• y= 200x + 1500

• y= -200x + 1500

There were approximately 11,000 students enrolled at Western Carolina last year. This figure goes up about 225 each year. Write a function to model this situation.

• y= -225x+ 11000

• y= 225x+ 11000

• y= 225x- 11000

• y= 11000x+ 225

Your new job is at the Custom T- Shop, where T-shirts are printed to order. For each order, Custom T Shop, charges $8.00 per shirt plus a one time set up fee of $15.00. Write a linear equation to show the relationship.

• y= -8x + 15

• y= 15x + 8

• y= -15x + 8

• y= 8x +15
