(-5, 1) and (-5, 7) PLEASE HELP I SUCK AT SLOPES

Slope formula can be determined through this equation,

y2 - y1 / x2-x1

Now we can pair these up

-5,1

-5 can be x1 and 1 be y1

Whilst

-5,7

-5 can be x2 and 7 can be y2

Now we follow formula

7-1 / -5- -5

6/0 is the slope

No slope

Step-by-step explanation:

Slope (m) = (change in the y-values)/ (change in the  x-values)

Slope (m) = (7 - 1) / [-5 - (-5)]

Slope (m) = 6/0

There is no slope because you can not divide by 0

b.an increase in a causes b to decrease

$30.32

step-by-step explanation:

65.00*.12=2.80

65.00-2.80=57.20

57.20*1.06=60.632

60.632/2=30.316
