Answer:
hey, good afternoon!
Explanation:
here is an example: the cost of a pizza is 7.50 and you can add a topping for 0.65 cents. find the cost of the pizza with 6 toppings
y=mx+b
the x stands for the toppings and y is the cost. the rate is 0.65 cents and the orginal amount of money is b. so the equation would look like this:
y= .65x+7.50. x=6
y = 65(6)+7.50
=3.9+ 7.50= $11.50(answer)
the m is the rate of change in this question is 0.65 cents
b is initial/ fixed/ value once again in this qeustion it 7.50$
hope this helps. have a great day!
