2. What is the equation for the table below: х
y
5
10
6
30
8
8
50

Step-by-step explanation:

We can tell this is a linear relation.

The slope is (50-30)/(8-6)=10.

So we have y=10x+b.

We can substitute in (5, 10) to get 10=10(5)+b -> b=-40

meaning y=10x-40

to complete this square you have to rotate about the origin 270 degrees clockwise.

answer: c

substitute in the values.

for a:

f(0) = 0 + 9

f(0) = 9

a is a solution.

for b:

f(7) = 14 + 9

f(7) = 23

b is a solution.

for c:

f (3) = 6 + 9

f(3) = 15

c is not a solution. it's supposed to be 14.

for d:

f(2) = 4 + 9

f(2)= 13

d is a solution.
