Determine the standard form of the equation of the line that passes through (6, – 9) and (-8, 6).
muminat

Answer:

15x + 14y = -18

Step-by-step explanation:

slope = (6 - -9)/(-8 - 6) = 15/-14

y = mx + b

6 = -15/14(-8) + b

6 = 60/7 + b

b = -18/7

y = -15/14x - 18/7

15/14x + y = -18/7, multiply everything by 14

15x + 14y = -18

Identify the percent of change as an increase or decrease. Then find the percent of change. Round to the nearest tenth of a perc
bazaltina [42]

I'll do the first two problems to get you started. All problems shown will use the same formula.

===========================================

Problem 4

The formula to use is

C = 100*(B-A)/A

where

A = old value

B = new value

C = percent change

In this case, A = 12 and B = 36, so

C = 100*(B-A)/A

C = 100*(36-12)/12

C = 100*(24/12)

C = 100*2

C = 200%

We have a 200% increase. It is an increase because the value of C is positive.

===========================================

Problem 5

Use the same formula as in the previous problem. This time,

A = 75 is the old value

B = 25 is the new value

C = 100*(B-A)/A

C = 100*(25-75)/75

C = 100*(-50/75)

C = 100*(-2/3)

C = -66.6667%

C = -66.7%

The value of C is negative, so we have a percent decrease of roughly 66.7%
