Question

does the point (4, 9) satisfy the inequality y ≥ 2x + 1? yes no

Explanation:

Step1: Substitute x and y values

For the point \((4, 9)\), \(x = 4\) and \(y = 9\). Substitute into the inequality \(y\geq2x + 1\):
\(9\geq2(4)+1\)

Step2: Simplify the right - hand side

Calculate \(2(4)+1\):
\(2(4)+1 = 8 + 1=9\)

Step3: Check the inequality

Now we have \(9\geq9\), which is a true statement.

Answer:

yes
