Answer:

y=8x + 5

Step-by-step explanation:

The y-intercept (b) in the equation y=mx+b is your starting price (5)

The m (slope) is change in change in y/ change in x. We know that the #of pizzas is the independent variable (x) , since it is the constant. From the table, one pizza is $8. The x in y=mx+b is for a variable of how many pizzas, but you dont need to worry about that since you're not solving for it.

Therefore,

y=8x+5

Answer:

y=8x+5

Step-by-step explanation:

The number of pizzas is your x value and the cost is your y value. To make an equation (y=mx+b) you first need to find the slope using two coordinates, so let’s use (0,5) and (1,13). (Y2-y1)/(x2-x1) equals (13-5)/(1-0) which equals 8, so your slope (m) is 8. Now you need to find your b. Let’s use the coordinate (0,5). Y=mx+b equals 5=(8)(0)+b which equals 5 so b is 5. Your equation is y=8x+5.
