Question 3 of 10

MrMuchimi

Answer:

The point-slope form of the line is:

$y + 4 = 4(x+3)$

Hence, option B is correct.

Step-by-step explanation:

We know the point-slope form of the line equation is

$y-y_1=m\left(x-x_1\right)$

where

m is the slope of the line

(x₁, y₁) is the point

Given

The slope m = 4

From the graph, we can take the point (-3, -4)

So, in our case:

(x₁, y₁) = (-3, -4)

m = 4

now substituting m = 4 and (x₁, y₁) = (-3, -4) in the point-slope form of the line equation

$y-y_1=m\left(x-x_1\right)$

$y - (-4) = 4(x - (-3))$

$y + 4 = 4(x+3)$

Therefore, the point-slope form of the line is:

$y + 4 = 4(x+3)$

Hence, option B is correct.

The graph of the line is also attached.

What is the functions average rate of change over each interval?

telo118 [61]

we can use average rate of change formula

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

(a) x = -3 to x = -2

Firstly, we will find points

(-3, 0) and (-2,2)

now, we can plug these values into formula

and we get

$=\frac{2-0}{-2+3}$

$=2$

(b)x = -2 to x =1

Firstly, we will find points

(-2,2) and (1,-4)

now, we can plug these values into formula

and we get

$=\frac{-4-2}{1+2}$

$=-2$

(c) x = 0 to x =1

Firstly, we will find points

(0,-3) and (1,-4)

now, we can plug these values into formula

and we get

$=\frac{-4+3}{1-0}$

$=-1$

(d) x = 1 to x =2

Firstly, we will find points

(1,-4) and (2,0)

now, we can plug these values into formula

and we get

$=\frac{0+4}{2-1}$

$=4$

(e) x = -1 to x =0

Firstly, we will find points

(-1,0) and (0,-3)

now, we can plug these values into formula

and we get

$=\frac{-3-0}{0+1}$

$=-3$

(f) x = -1 to x =2

Firstly, we will find points

(-1,0) and (2,0)

now, we can plug these values into formula

and we get

$=\frac{0-0}{2+1}$

$=0$

Lee filled up his gas tank before starting a road trip. If he used 5.8 gallons two hours into the trip, and has 12.4 gallons rem

Cloud [144]

The answer would be 18.2 gallons because they used up 5.8 gallons, they still have 12.4 gallons that they did not use and in order to get the original amount of gas they had before the trip, you would add up 12.4 and 5.8 to get the Original amount. Hope this helps.
