Find the equality represented by the graph?

Answer:
[tex]-x+4y<12[/tex]
Step-by-step explanation:
Given: graph
To find:the inequality
Solution:
Equation of a line passing through points [tex](x_1,y_1),(x_2,y_2)[/tex] is given by [tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
Take [tex](x_1,y_1)=(0,3),(x_2,y_2)=(4,4)[/tex]
So,equation of line is evaluated as follows:
[tex]y-3=\frac{4-3}{4-0}(x-0)\\ y-3=\frac{x}{4}\\ 4y-12=x\\-x+4y=12[/tex]
As per the graph,inequality is [tex]-x+4y<12[/tex]
Here, use sign < and not [tex]\leq[/tex] as line in the graph is dotted that is points on the line are excluded.
