Slope = (change in 'y') / (change in 'x')
If you find two points where the line goes through the corners of boxes,
then count up the 'y' boxes and the 'x' boxes between those two points,
you'll find that the line rises 3 y-boxes for each x-box.
The slope of the line is 3 .
So, you divide 18 by 12 to get 1.5
but since you want the fraction, just reduce 18/12 as much as possible to get 3/2
Since the value is taken from a population, the value is a parameter.
<h3>Parameter and Statistic:</h3>
- If the information is taken from a sample, it is called a statistic.
- If the information is taken from a population, it is called a parameter.
For this problem, the students of the class are the population, as all students are considered for the calculator of the mean, hence the value is a parameter.

Answer:
Perimeter: 6x+8
Area: 2x²+8x
Step-by-step explanation:
Perimeter- the sum of all sides
So, you do x+4+x+4+2x+2x
Simplify that to- 2x+2x+2x+8
And also simplify that to- 6x+8
Area- length*width
So, it's (x+4)*2x
which is 2x²+8x
