The ice cream store sells sundaes. Each sundae costs $2.50 plus $0.35 for each topping. Find the rate of change and initial valu

Kobotan [32]

Answer:

rate of change: $0.35; initial value: $2.50; Equation: y= 0.35x + 2.50

Step-by-step explanation:

The rate of change is $0.35 because it's the one to change the total cost of the ice cream. If you get 3 toppings, you'll end up with 1.05 more dollars than if you had 0 toppings. And because of that, the initial value would also be $2.50, that's the minimum price you'll have to pay if you do want a sundae.

The equation is just restating all that, you start with the inital value b=$2.50, and the price will go up by 0.35 for every topping you add to the sundae.

Hope this helped :)

Since the points are collinear, they all lie on the same line and have the same slope between them.

Calculate the slope m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$
