Answer with explanation:
Equation of line passing through the points (1, 4) and (2, 9) is given by
Formula
[tex]\frac{y-y_{1}}{x-x_{1}}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\\text{Equation of line}\\\\\frac{y-4}{x-1}=\frac{9-4}{2-1}\\\\y-4=5(x-1)\\\\y-4=5x-5\\\\5x-y-5+4=0\\\\5x-y-1=0[/tex]
Now it is given that we have to shade below the line.
The most appropriate option among three is,
Option C:→5x − y greater than or equal to 1
