Question

Is (3,6) a solution of y's 3x + 4?

Answer 1

Step 1:

(3,6) means x coordinate is 3 and y coordinate 6

Step 2:

We substitute the values of x = 3 and y = 6 into the inequality

`\begin{gathered} y\text{ }\leq\text{ }(2)/(3)\text{ }x\text{ + 4} \\ 6\text{ }\leq\text{ }(2)/(3)\text{ x }(3)/(1)\text{ + 4} \\ 6\text{ }\leq\text{ 2 + 4} \\ 6\text{ }\leq\text{ 6} \end{gathered}`

Conclusion:

Since 6 is equal to 6, then (3,6) is a solution of the given Inequality
