First you must find slope using two points (2,7.5) and (-1,0).
0-7.5 = -7.5
-1-2 = -3
-7.5/-3 = 2.5
y - 0 = 2.5 ( x + 1)
y - 0 = 2.5x + 2.5
y = 2.5x + 2.5
y = 2.5x + 2.5

Luba_88 [7]

Answer:

Step-by-step explanation:

(5, -30)  (6, -36)

(-36 + 30)/(6 - 5) = -6/1 = -6

y + 30 = -6(x - 5)

y + 30 = -6x + 30

y = -6x + 0

y = -6x

Mr. Babe used to work at a local furniture store.
8090 [49]

A. Mr. Babe made a commission of $14.85

B. He makes $15.75 per hour after the raise.

Step-by-step explanation:

A. While he worked there, Mr. Babe earned 3% on how much he sells. If he sold $495 couch, how much commission did he make?

Worth of sold couch = $495

Commission = 3%

Amount of commission = 3% of total worth sold

Amount of commission = \frac{3}{100}*495

Amount of commission = \frac{1485}{100}=\$14.85

Mr. Babe made a commission of $14.85

B. On top of his commission, Mr. Babe made $15 per hour. He eventually got a raise with an increase of 5% per hour. After the raise, how much did he make per hour?

Amount earned per hour = $15

Increase = 5%

As the increment is on per hour amount, therefore,

Amount of increase = 5% of per hour amount

Amount of increase = \frac{5}{100}*15=\frac{75}{100} = \$0.75

New amount per hour = Per hour amount + amount of increase

New amount per hour = 15+0.75 = $15.75

He makes $15.75 per hour after the raise.

Serggg [28]

Answer:

b = 0.0138

Step-by-step explanation:

Given

Regression Equation:

DD=2.69+0.0138D

Required

Determine the slope of the regression line

The equation of regression is of the form

Y =  a + bX

Where b represents the slope;

Compare Y =  a + bX to the given equation

DD=2.69+0.0138D

We have that:

Y = DD

a = 2.69

b = 0.0138

X = D

Hence; the slope is:

b = 0.0138
