Answer:
Option C is the answer.
Step-by-step explanation:
To find the equation of the straight line equation i.e, we must be given with the two points
and 
Since from the graph the two points closest to the line are
and 
Equation of line with two points closest to the line :

where m is the slope.
First we find the slope(m)=

on simplify we get,
.
Now, to find the equation of the line: 

Apply distributive property on right hand side, we get
Adding both sides by 36, we get

.
The equation for the linear model in the scatter plot obtained by the two closest point
closest to the line is,

1.Identify the fractions. Using the distributive property, you’ll eventually turn them into integers.
2.For all fractions, find the lowest common multiple (LCM) -- the smallest number that both denominators can fit neatly into. This will allow you to add fractions.
3.Multiply every term in the equation by the LCM.
4.Isolate variables adding or subtracting like terms on both sides of the equals sign.
5.Combine like terms.
6.Solve the equation and simplify, if needed.
Answer:
22.5%
Step-by-step explanation:
The total number of students in percentage terms is 100%
Students that chose others = 100% - 40% - 37.5% = 22.5%
All the numbers are tilted at a 90 degree angle, except for the number 4 which it tilted at an angle of 89 degrees, hoped this helps
