Here is the formula and solution.

The first thing you have to do is:

subtract: 11-5

Then subtract: -4-(-2)
 
then you put it as a fraction:  6/-2 or -3

That -3 would be considered the slope.

So now you have: y=-3x+ b

So what you have to do is plug in one of the points into the equation to find out what b is.

For example:  11 = -3(-4) + b 
                                   11=12 + b
                                    -12   -12
                                        b = -1
So the answer is: y = -3x -1

Answer:

2 + m- 1 + m

Step-by-step explanation:

3m +1 -m

Combine like terms

3m-m +1

2m +1

We can split the m's

m+m +1

And we can rewrite 1 as 2-1

m+m+2-1

m+2+m-1

Rearranging the order

Solve for x. 4x − 33=7
tatuchka [14]

Note the equal sign. What you do to one side, you do to the other.

Do the opposite of PEMDAS. First, add 33 to both sides

4x - 33 (+33) = 7 (+33)

4x = 40

Next, divide by 4

4x/4 = 40/4

x = 40/4

x = 10

10 is your answer

hope this helps
