If you know the slope of a linear relationship as well as one of the points, you can determine if the relationship is proportional if the value of y is equal to the value of the slope times the x value. 
<h3>When is a relationship proportional?</h3>
The linear relationship of x and y is said to be proportional if: 
y = slope × x 
This means that the value of y is directly related to the value of x such that when x is increased by a certain value, you get y. 
If this condition is not satisfied then the relationship is not proportional. 
The linear relationship above is therefore proportional if the value of y in the point is the same as x when multiplied by the slope.

Step-by-step explanation:
Let's get our relevant base equations listed out:
d = 2r
area = pi*r²
c = πd
Thus, d=2*5m  = 10m, c=π*10m=10π m, and area = 25m²*π

The mathematical expression in this case is
(x+3)/2
        
             
        
        
        
Total number of students who did a test was 24
Number of students who scored an A is 14
Number of students who scored a B is 10
Probability that when we randomly select a student, he/she will have an A is:
(Number of students that scored A)/(Total number of students)
=14/24
=7/12
Therefore our answer is 7/12
