What is the approximate equation of this line of best fit in slope-intercept form?

Answer:

Step-by-step explanation:

y = negative 13 over 10x + 13 is the best choice. (0, 13) is the y-intercept. If we begin at (0, 13) and move approximately 10 units to the right, y decreases by 13, so the slope is m = -13/10.

Writing y = negative 13 over 10x + 13 as y = negative 13 over 10 plus 13 would be clearer. We must emphasize that the slope is -13/10 and that this should be enclosed in parentheses: y = (negative 13 over 10)x + 13.

Find the average rate of change for the function f(x) =x^2 -6x+2 on the closed side interval (-5,2)

s344n2d4d5 [400]

Answer:

- 9

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

$\frac{f(b)-f(a)}{b-a}$

Here [a, b ] = [ - 5, 2 ], thus

f(b) = f(2) = 2² - 6(2) + 2 = 4 - 12 + 2 = - 6

f(a) = f(- 5) = (- 5)² - 6(- 5) + 2 = 25 + 30 + 2 = 57 , thus

average rate of change = $\frac{-6-57}{2-(-5)}$ = $\frac{-63}{7}$ = - 9

Jane has a pre-paid cell phone with Splint. She can't remember the exact costs, but her plan has a monthly fee and a charge for

yan [13]

Answer:

The costs of the plan are $0.15 per minute and a monthly fee of $39

Step-by-step explanation:

Let

x ----> the number of minutes used

y ----> is the total cost

step 1

Find the slope of the linear equation

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

we have the ordered pairs

(100,54) and (660, 138)

substitute

$m=\frac{138-54}{660-100}$

$m=\frac{84}{560}=\$0.15\ per\ minute$

step 2

Find the equation of the line in point slope form

$y-y1=m(x-x1)$

we have

$m=0.15\\point\ (100,54)$

substitute

$y-54=0.15(x-100)$

step 3

Convert to slope intercept form

Isolate the variable y

$y-54=0.15x-15\\y=0.15x-15+54\\y=0.15x+39$

therefore

The costs of the plan are $0.15 per minute and a monthly fee of $39
