I WILL GIVE BRAINLIEST AND 50 Calculate the rate of change for the following data:
x y
-1 7
2 -2
7 -17
10 -26

HELP

we get Rate of change = -3

Step-by-step explanation:

We need to calculate the rate of change for the following data:

x     y

-1     7

2     -2

7     -17

10   -26

The rate of change can be calculated using slope formula:

From the table, we can take any 2 points

Suppose we take (-1,7) and (2,-2)

We have:

Putting values in formula and finding rate of change

So, we get Rate of change = -3

x+y=90

x=30-y=x

step-by-step explanation:

if you understand you will get the answer

step-by-step explanation:

this is not a question
