Jeanettes ticket was less than the original price by 28%

Step-by-step explanation:

The original price of the ticket was $75. She used a coupon code to receive a 20% discount. This means that the amount of discount that she got is

20/100 × 75 = 15

The discounted price would be

75 - 15 = $60

The website apply to 10% service fee to the discounted price. This means that the amount of service fee charged by the website is

10/100 × 60 = $6

The final cost of the ticket is

60 - 6 = $54

The difference between the final price and the original price is

75 - 54 = 21

The percentage difference in the prices would be

21/75 × 100 = 28%

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0

no association

step-by-step explanation:

if you have eyes and you can use them efficiently you can see that it just looks like random dots like do a line of best fit and like they're so spread out it's such a weak association you might as well consider it nonexistent
