You plot the points on the graph first with a pencil. Draw the given line, in this case, it's y=-x.
From a point, you do rise and run to the line and reverse it on the other side of the line to get the points.
Refer the attached diagram, for easy method.
Hope it helps :)
For this case we have the following equation:

We can rewrite the equation.
For this, we subtract 2.2 on both sides of the equation.
We have then:

Rewriting the equation on both sides we have:

This obtained equation is an equation equivalent to the initial equation.
Answer:
An equation that is equivalent is:
You can use the equation x/700 * 2/100 to get your answer.
700 * 2 = 1400
1400/100 = 14
So 14 students at the school have red hair.
Using it's concept, the experimental probability that the next client to get a haircut Manuel's salon will have brown hair is 1/2.
<h3>
What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>. For an experimental probability, these number of outcomes are taken from previous trials.
In this problem, out of 12 haircuts, 6 were with brown hair, hence the probability is given by:
p = 6/12 = 1/2.
