Omar is designing Chromebook covers as a fund-raising project for math class.

The cost of printing is $500, plus $9.50 per cover.  

What is the y-intercept (starting point)?

• $500

• $9.50

• $509.50

• $490.50

The cost of printing is $500, plus $9.50 per cover.  

What is the equation for this line?

Let x be the number of covers and y be the total cost. 

• y=9.50+500x

• x=500+9.50y

• y=9.50x+500

• y=509.50x

You found the equation to be y = 9.50x + 500

How much would it cost to print 100 covers?

• $609.50

• $509.50

• $5000

• $1450.00

You found the equation to be y = 9.5x + 500
