Sagot :
[tex]y\leq2x+4[/tex]
We will substitute x by the x-coordinate of the given point and check the value of y
At x = 0
[tex]\begin{gathered} y\leq2(0)+4 \\ y\leq0+4 \\ y\leq4 \end{gathered}[/tex]The value of y = 6
and 6 not smaller than or equal 4
(0, 6) not a solution
At x = 2
[tex]\begin{gathered} y\leq2(2)+4 \\ y\leq4+4 \\ y\leq8 \end{gathered}[/tex]The value of y is 3
3 is smaller than 8
(2, 3) is a solution to the inequality
Let us check the other points
At x = -4
[tex]\begin{gathered} y\leq2(-4)+4 \\ y\leq-8+4 \\ y\leq-4 \end{gathered}[/tex]The value of y is 1
1 is not smaller than -4
(-4, 1) not a solution to the inequality
At x = 0
[tex]\begin{gathered} y\leq2(0)+4 \\ y\leq0+4 \\ y\leq4 \end{gathered}[/tex]The value of y = 4
4 is equal to 4
(0, 4) is a solution to the inequality also
