how to try the values of the x and y

Equation of a line:  y = mx + c,  where m is the slope and c is the y-intercept. To calculate the slope, we do so using the formula: m = \frac{y2 - y1}{x2 - x1}

Now plugging in our values, m = \frac{4 - (-3)}{-7 - (-2)}  = \frac{4 + 3}{-7 + 2} = \frac{7}{-5} = \frac{-7}{5}

So our slope m, is = -7/5

We can now input the value of the slope. But in this question, we cannot use the above equation of a line since we are asked to use a point-slope equation expression, so the equation is y - y1 = m(x - x1)

Now we plug in our values,

y - (-3) = \frac{-7}{5}(x -  (-2))\\y + 3 = \frac{-7}{5}(x + 2)

So the answer should be option D.

13. Write a rule for the linear function in the table.
dalvyx [7]

Answer:

(x)= 2, 5, 8, 11

Use the formula  

a n  =  a 1  +  d  ( n  −  1 )

to identify the arithmetic sequence.

a n  =  3 n  −  1

f(x)= 5, 11 17, 23

Use the formula  

a n  = a 1  +  d  ( n − 1 )

to identify the arithmetic sequence.

a n  =  6n  −  1

x      f(x)

2      5

5      11

8      17

11      23

Nothing further can be done with this topic. Please check the expression entered or try another topic.

2 ,   5 ,   8 ,   11  

5 ,   11 ,   17 ,   23

Step-by-step explanation:

Write a rule for the linear function in the table.

x;     f(x)

2      8

5     17

5      11

11    23

A; f(x) = x + 5

B;f(x) = x + 1

C;f(x) = 2x + 1

D;f(x) = –2x – 1

If all your solutions are  

A; f(x) = x + 5

B;f(x) = x + 1

C;f(x) = 2x + 1

D;f(x) = –2x – 1

None of the above will work with the data set you have presented.

HELP MEEEE PLEASE IM BAD WITH WORD PROBLEMS
patriot [66]

He worked 36 hours (9.57), and anything over that was over pay (14.36)

36 * 9.57 = 344.52

So, working his normal hours he got $344.52.

416.32 - 344.52 = 71.80

71.80/14.36 = 5

Therefore, he worked 5 hours of overtime.

Freddy drilled into a piece of wood and a joist to attach them. He drilled 4 inches and the wood was 1 1/3 inches thick.
Angelina_Jolie [31]

The depth of the joist that was drilled by Freddy is 5 1/3 inches.

From the information given, we are informed that Freddy drilled into a piece of wood and a joist to attach them and that be drilled 4 inches and the wood was 1 1/3 inches thick.

Therefore, to get the depth that was drilled, we'll need to add the fractions given together. This will be:

= 4 + 1 1/3

= 5 1/3 inches.

Therefore, the depth of the joist that was drilled by Freddy is 5 1/3 inches.

A group of artists is selling small prints to raise money for charity. They sell p prints, and make a profit of f(p) on the sale
liraira [26]

The correct answer is is D) If the group sells 15 prints they will loose $85.

To figure out which statement is true, we have to evaluate the function ,

p(x)=17x-340 for all the values given in options (A)-(D).  A negative output represents a loss and  a positive output will represent a profit.

In A p=12 so f(12)=17\times 12-340=-136. In this case we gather that if they sell 12 prints, they will make a loss of $136. This tells us that option A is wrong.

In B, p=28 so f(28)=17\times 28-340=136. In this case we gather that if they sell 28 prints, they make a profit of $136. This tells us that option  B is wrong.

In C, p=35 so f(35)=17\times 35-340=225. In this case we gather that if they sell 35 prints, they make a profit of $225. This tells us that option  C is wrong.

Lastly, p=15 so f(15)=17\times 15-340=-85. In this case we gather that if they sell 28 prints, they make a loss of 85 dollars. From this we gather that D is the correct option.
