Solve the system of equations

2x- 6y= 28
-x-y = 14

A) 2x- 6y= 28

B) -x-y = 14

Multiply equation B) by 2

B) -2x  -2y = 28  than add it to A)

A) 2x - 6y = 28

-8y = 56

y = -7

b) -x -y = 14

-x = 14  -7

x = -7

Step-by-step explanation:

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2
