Answer:
Slope = -2
Step-by-step explanation:
x1 y1 x2 y2
(-1 , 9) (2 , 3)
Slope = <u>y2 - y1</u>
x2 - x1
<u>3 - 9 </u>= <u> -6 </u>
2 -(-1) = 3
= -2
Answer:

Answer:The percent decrease was 15%
Step-by-step explanation:
In order to find this, use the percent change equation.
(New - Old)/(Old) * 100 = % Change
Now input 149.42 for the New price and 175.80 for the Old price.
(149.42 - 175.80)/(175.80) * 100 = % Change
-26.38/175.80 * 100 = % Change
-.15 * 100 = % Change
-15 = % Change
Step-by-step explanation:
