Use the equation to find the slope: m=y2-y1/x2-x1 and plug in each of the y coordinates into the numerator and each of the x coordinates in the denominator

m=-2-3/4-8
-5/-4
m=5/4

Plug in the slope and one of the ordered pairs into y=mx+b. I’ll use (8,3)

3=5/4(8)+b
3=10+b
-7=b

Equation: y=5/4x-7

An employee shreds 341 pages in 11 minutes of work. How many pages will she shred in 20 minutes?
gavmur [86]

We have been given that an employee shreds 341 pages in 11 minutes of work.

First of all we will divide 341 by 11 to find number of pages shred by employee in one minute.

\text{Pages shred by employee in one minute}=\frac{341}{11}=31

Now let us multiply 31 by 20 to find number of pages shred by employee in 20 minutes.

\text{Pages shred by employee in 20 minutes}=31\cdot20=620

Therefore, employee will shred 620 pages in 20 minutes.

Multiply me by 4 then subtract 13 if you divide me by 3 and add 17 you get 22
8_murik_8 [283]
You have to do the opposite

22-17=5
5x3=15
15+13=28
28/4=7

The answer is 7. You can check this by doing what it says and if it makes 22, it’s correct. (I’ve already checked it) :)
