Answer:

B

Step-by-step explanation:

Hey There!

they are asking for the equation in slope intercept form

Slope intercept form is y=mx+b

where m equals slope and b equals y intercept

to find the slope we do change in y over chang in x

as y goes up 2 x goes down 5 so the slope would be -2/5

the y intercept is at (0,4) so the y intercept is 4

now we add everything together and get that the equation in slope intercept form is

y=-2/5x+4

so we can conclude that the answer is B

Answer:

Step-by-step explanation:

A line can be expressed as

y=mx+b, where m is the slope and b is the y intercept (the value of y when x=0)

Any two points form a line when connected.

m=(y2-y1)/(x2-x1), in this case we have points (0,4) and (5,2) so

m=(2-4)/(5-0)

m=-2/5 so our line is now

y=-2x/5+b, using (5,2) we can solve for b

2=-2(5)/5+b

2=-2+b

b=4, so the line is

y=-2x/5+4

Answer B

Lovely Lawns, Inc., intends to use sales of lawn fertilizer to predict lawn mower sales. The store manager estimates a probable
12345 [234]

Answer:

R = 0.8815 ;

y = 6.14679X + 2.33028 ;

14.624

Step-by-step explanation:

Using an online correlation Coefficient calculator, the correlation Coefficient, R between the number of lawn fertilizer sold and the number of lawn mowers sold is 0.8815. This R value depicts a strong positive correlation between both variables.

The regression line equation obtained by Plotting the values to generate a linear model is :

y = 6.147X + 2.330

With ;

Slope or gradient being 6.147

Intercept = 2.330

C.)

x = 2

y = 6.147X + 2.330

y = 6.147(2) + 2.330

y = 14.624

What is the average rate of change of f<br> over the interval (-5,0]?<br> Give an exact number.
Paraphin [41]

Answer:

Average rate of change = 0.6

Step-by-step explanation:

Average rate of change of a function between x = a and x = b is given by,

Average rate of change = \frac{f(b)-f(a)}{b-a}

From the graph attached,

f(-5) = 0

f(0) = 3

Average rate of change of the graph between x = -5 and x = 0,

Average rate of change = \frac{3-0}{0-(-5)}

                                        = \frac{3}{5}

                                        = 0.6

Therefore, average rate of change of the given function between x = -5 and x = 0 is 0.6.
