What does the slope mean in the context of the problem?

• The cost will increase by $1.40 per topping

• The cost will decrease by $1.40 per topping

• The cost will increase by $1.90 per topping

• The cost will decrease by $1.90 per topping 

What is the meaning of the y-intercept?

• The hamburger will cost $1.90 without any toppings.

• The hamburger will cost $1.40 without any toppings. 

• The cost of the hamburger is $1.90 with one topping

Write the equation of the line in slope-intercept form.

• y = -5/7x - 2.5

• y = 7/5x - 2.5

• y = -7/5x - 2.5

• y = 5/7x - 2.5
