The difference between two numbers are
and numbers are
and
so the equation is 
How to find the equation and what is the equation ?
equation, statement of equality between two expressions consisting of variables and/or numbers. In essence, equations are questions, and the development of mathematics has been driven by attempts to find answers to those questions in a systematic way.
if the difference of two numbers are 
And one number is
and another is 
So we write the equation with operation of subtraction

The formula of a midpoint of a segment AB:

We have:
H(10; 1); K(4; 7)
substitute:

Answer: (7, 4)
We know that
<span>If each window covering covers 15 windows, and there are a total of 50 windows to be covered,
it will take -------> 50/15=3.33 windows coverings
</span>So,
you need more than 3 coverings,
and so take the next whole number --------> 4 window coverings
the answer is
4 window coverings

We are asked to find the slope of the line that is parallel to the line
.

- Parallel lines have the same slope.
So let's first determine the slope of the first line, and then let's find the slope of the line that's parallel to it.

- The slope is the coefficient of x.
So the slope is
.
Can you guess the slope of the line that is parallel to the first line?
That's right! The slope is...

Hope it helps you out! :D
