What is the slope of the line in the graph?
a. -4/3
b. -3/4
c. 3/4
d. 4/3

To find the slope you have to use this formula:

First chose any 2 random points from the graph, im gonna chose (0,1) and (-4,4). It doesn't matter which one is the x1 or x2, what matter is they have to be in the same order, you can't have (-4,4) as a (x1,y2), That's wrong.

= -3/4

b, i believe, but not sure.

a) at most means it can cost $12 or less

so the inequality sign would be ≤

you would then need to multiply the number of toppings by the 0.35 for each one and add it to the cost of the cheese pizza.

the equation would be 9.99 + 0.35x ≤ 12

b) using the above equation:

9.99 + 0.35x ≤ 12

subtract 9.99 from each side:

0.35x ≤2.01

divide both sides by 0.35:

x ≤ 2.01 / 0.35

x ≤5.74

at most you could have 5 toppings.

the 5 topping pizza would cost: 0.35 x 5 = 1.75 + 9.99 = $11.74
