Answer:

Number 7: m=\frac{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=\frac{-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.

Step-by-step 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=\frac{y^2-y^1}{x^2-x^1}

m=\frac{17-11}{6-2}

Step 3: Subtract.

m=\frac{6}{4}

Step 4: Simplify.

improper fraction: \frac{3}{2}

mixed number: 1\frac{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=\frac{y^2-y^1}{x^2-x^1}

m=\frac{800-1200}{6-3}

Step 3: Subtract.

m=\frac{-400}{3}

Step 4: Simplify.

Cannot be simplified further.

mixed number: m=\frac{-400}{3}

decimal: 133.333333333

Answer:

x = 44°

Step-by-step explanation:

The sum of the three angles is 180°.

So, x + x + 5 + 2x -1 = 180

4x + 4 = 180

4x = 176

x = 44°
