Answer: 0.5

Step-by-step explanation: To find the average, we begin by adding the numbers so we have -3 + 0 + 7 + -2 which is 2.

Now we divide 2 by the number of numbers in the data set which is 4.

2 divided by 4 is 0.5 so the average of these numbers is 0<em>.</em>5.

Answer:

Firstly you need to put the equation in form of. y =ax+b

Let us do it

We have

2x-2y=18

-2y=18-2x

-y=(18) /2 - (2x)/2

-y =9-x

Mutiply by - to remove it beside y

Y=-9+x

Which is y=x-9

Slope =a=1

Yintercept=b=-9

How to find the midpoint in a segment

Brilliant_brown [7]

Answer:

$\text{Segment midpoint formula}$

Step-by-step explanation:

$(\frac{x1 + x2}{2},\frac{y1+y2}{2})$

For example:

$\text{Points: } (4,9) (8,4)$

As long as you appropriately place the X and Y points, it doesn’t matter which $x \underset{1}$ etc you use.

$(\frac{4+8}{2},\frac{9+4}{2}) = 6, 6.5$

$\text{X midpoint: 6}\\\text{Y midpoint: 6.5}$
