Question

PLEASE I NEED HELP WITH THIS I WILL MARK AS BRILLIANT PLS!!

**(You have to show how do you solve the answer and explanation too not only the answers, so m basically show your work)** !!

Thanks :)

Answer 1

Number 7:
`m=(6)/(4)`

This graph displays the change in wage per years of service. Since the slope is positive, this means the wage has a positive growth.

Number 8:
`m=(-400)/(3)`

This graph displays the amount of people evacuating per hour. Since the slope is negative, this means the amount of people evacuating per hour is reducing.

Explanation:

Number 7:

Step 1: Identify the points on the line to use for slope formula.

The two points are (2, 11) and (6, 17).

`x^1` and
`y^1` will be
`(2,11)`

`x^2` and
`y^2` will be
`(6, 17)`

Step 2: Plug in points into slope formula.

`m=(y^2-y^1)/(x^2-x^1)`

`m=(17-11)/(6-2)`

Step 3: Subtract.

`m=(6)/(4)`

Step 4: Simplify.

improper fraction:
`(3)/(2)`

mixed number:
`1(1)/(2)`

decimal:
`1.5`

Number 8:

Step 1: Identify the points on the line to use for the slope formula.

The two points are (3, 1200) and (6, 800)

`x^1` and
`y^1` will be
`(3,1200)`

`x^2` and
`y^2` will be
`(6, 800)`

Step 2: Plug in points into slope formula.

`m=(y^2-y^1)/(x^2-x^1)`

`m=(800-1200)/(6-3)`

Step 3: Subtract.

`m=(-400)/(3)`

Step 4: Simplify.

Cannot be simplified further.

mixed number:
`m=(-400)/(3)`

decimal:
`133.333333333`
