Which number line shows the solution to the inequality? y - 2 < -5

Tatiana [17]

For this case we have the following inequality:
$y - 2 \ \textless \ -5
$
We will solve the inequality algebraically.
We have then:
We add 2 to both sides of the inequality:
$y - 2 + 2 \ \textless \ -5 + 2
$
Rewriting we have:
$y \ \textless \ - 3
$
Therefore the solution is:
(-inf, -3)
Answer:
(-inf, -3)
