Answer:

Not a solution

Step-by-step explanation:

y ≥ 2x + 5

=> Substituting x = 2 and y = -1 in Equation,

=> -1 ≥ 2(2) + 5

=> -1 ≥ 4 + 5

=> -1 ≥ 9 [Not possible]

Therefore, (2,-1) is not a solution of y ≥ 2x + 5

krok68 [10]

ANSWER

$y \geqslant \frac{1}{4} x - 1$

EXPLANATION

The graph has a solid boundary line.

The region above the boundary line is shaded

Therefore the inequality sign involved is '≥'

The boundary line has equation

$y = \frac{1}{4} x - 1$

We can now conclude that, the inequality graphed above is

$y \geqslant \frac{1}{4} x - 1$
