Answer:

Y = 14

Step-by-step explanation:

1/2(-9 + y) = 2.5

1/2 * -9 = -4.5

1/2 * y = 0.5y

-4.5 + 0.5y = 2.5

+4.5             +4.5

0.5y = 7

/0.5   /0.5

y = 14

Answer:

\frac{1}{2} ( - 9 + y) = 2.5 \\  - 4.5 + 0.5y = 2.5 \\ minus \:  - 45 \: both \: sides \: of \: the \: equation \\  \frac{0.5y}{0.5}  =  - \frac{ 7}{0.5}  \\   y =  14

Draw the graph of the equation<br><br> x+y=5
Advocard [28]

well first you have to get x and y on separate sides so subtract x by both sides to put x on the right side.

now you have y = 5 - x

to graph that let's throw in some numbers for x and y and make a function table

x, y

1, 4

2, 3

3, 2

4, 1

5, 0

6, -1

and so forth

as you can see as x increases in value, y decreases in value

all you have to do now is plot those points on a graph
