Let's first calculate the slope, which is taken by dividing the change in y by the change of x.

6-4=2

4-3=1

The slope is 2.

Now that we know the slope is 2, we can plug in two coordinates to solve for the y-intercept, represented as b.

Let's pick (3,4).

So, y=2x+b

4=6+b

-2=b

The equation is 2x-2

Check: 4=(2*3)-2

I'm assuming you are trying to simplify the expression.

Distribute the -1 to both terms in the parentheses like so:

-1*-2=2

-1*-x=x

2+x is simplest form.

Let m represent the number of muffins NIkos sold.

Since muffins are $0.75 each and he made $36.75, the equation is 

0.75m=36.75

14.7^2=216.09=216 9/100

There aren't any like terms or a GCF, so the expression is already simplified.

Multiply 1 by itself 10 times, which is one.

4^2=4*4=16.

Your question is unclear. Perhaps you are trying to find out the number of miles per day?

If that's the case, take 1020 and divide by 120.

Since you know the area of the square, the length of any side is the square root of 9 square inches, which is three inches.

2*1=2

adding the five zeros, 100*2000=200,000
