Aconsumer has $100 per day to spend on product a, which has a unit price of $7, and product b, which has a unit price of $15. what is the slope of the budget line if good a is on the horizontal axis and good b is on the vertical axis?

-15/7

Step-by-step explanation:

Let B(x1, y1) be on vertical (y-axis) then B = (0, 15) and

A(x2, y2) be on horizontal (x-axis) then A = (7, 0).

Now, slope = (y2 - y1)/(x2 - x1)

then slope = (0 - 15)/(7 - 0)

=> slope = (-15)/7

slope of the budget = -15/7

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value
