Answer:
[tex]S=\frac{C}{2}[/tex]
Step-by-step explanation:
From the graph B,
Let the equation of the line representing the relation between hours spent in studying 'S' and hours spent in class 'C' is,
S = mC + b
Where m = Slope of the line
b = y-intercept of the line
We choose two points (2, 1), and (4, 2) lying on the line.
Slope 'm' = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
m = [tex]\frac{2-1}{4-2}[/tex]
m = [tex]\frac{1}{2}[/tex]
y-intercept 'b' = 0
Equation of the line will be
S = [tex]\frac{1}{2}C[/tex]
