Answer:

Slope of the line passing through the given points are: \frac{1}{4}

Step-by-step explanation:

Slope of a line : For any two point (x_1, y_1) and (x_2, y_2)

the formula of slope is given by:

Slope(m) = \frac{y_2-y_1}{x_2-x_1}

Given the points ( -4, 7) and (0, 8)

then, by using slope formula;

m = \frac{8-7}{0-(-4)} = \frac{1}{0+4} = \frac{1}{4}

Therefore, the slope of the line passing through the given points are: \frac{1}{4}

<u>Answer:</u>

1 / 4

<u>Step-by-step explanation:</u>

We are to find the slope of a line which passes through the two given points: (–4, 7) and (0, 8).

We know the formula of the slope (m):

slope = \frac{y_2-y_1}{x_2-x_1}

So putting in the values of the coordinates of the given points in the formula to get:

Slope = \frac{8-7}{0--4} = \frac{1}{4}

Therefore, the slope slope of a line which passes through the two given points: (–4, 7) and (0, 8) is 1 / 4.

What is the answer to this question
densk [106]

Answer:

- 1, 1, - 3

Step-by-step explanation:

To obtain the value of f(1), we require the corresponding value of y from the graph when x = 1

From the graph

when x = 1 the value of y on the graph is - 1 ⇒ f(1) = - 1

Similarly

f(3) means what is the value of y corresponding to x = 3

From the graph when x = 3 then y = 1 ⇒ f(3) = 1

and f(- 1) = - 3

Answer:  The cost of one rose bush is $7 and the cost of one shrub is also $7

Step-by-step explanation:

The situtation can be represented by the systems of the equations.

10x + 4y  =  98   x in this case is the cost of  one rose bushes

9x + 9y =  126     y  is the cost of one shrub.  

Solve the system of equation using the elimination method.

10x +4y = 98

9x + 9y = 126     eliminate the y variable so you will have to multiply 9 on top                                          and -4 down.

9(10x +4) = (98)(9)

-4(9x + 9y) = 126(-4)

You will now have the new two systems of equations

90x +36y = 882

-36x +-36y = -504    Now add the equations

0  + 54x = 378      

        54x = 378

  x= 7

Now we know that the cost of one rose bush is 7 so we will plot it into one of the equations and solve for the cost of one shrub.

90(7) +36y=882

630 +36y = 882

-630            -630

    36y = 252

   y = 7

Check:  10(7) + 4(7)= 98

              70  + 28 = 98

             98= 98  

so one rose bush is actually 7 dollars the same as 1 shrub.
