Answer:

b. The slope of the line

Step-by-step explanation:

To explain the question statement, first we view the pattern of regression of equation which is

Y=a+bx

Where Y is dependent variable and x is an independent variable.

a represents the Y-intercept and depicts the value of dependent variable y when independent variable x=0. b represents the slope in the regression equation and interpreted as unit change in dependent variable Y due to unit change in independent variable X.

A truck can be rented from Company A for $70 a day plus $0.20 per mile. Company B charges $20 a day plus $0.40 per mile to r

Otrada [13]

Answer:

For Company A to have a better deal, the truck must be driven more than 250 miles per day.

Step-by-step explanation:

Given that:

Rent per day of company A = $70

Per mile charges = $0.20

Let,

x be the number of miles.

A(x) = 0.20x + 70

Rent per day of company B = $20

Per mile charges = $0.40

B(x) = 0.40x + 20

For make Company A better deal,

A(x) > B(x)

0.20x+70 > 0.40+20

0.20x-0.40x>20-70

-0.20x>-50

Dividing both sides by -0.20

$\frac{-0.20x}{-0.20}>\frac{-50}{-0.20}\\x>250$

Hence,

For Company A to have a better deal, the truck must be driven more than 250 miles per day.
