Question

Solve the inequality. Then graph its solution. $y + 1 \ \textless \ - 1$

Answer 1

Let's solve this inequality:

y + 1 < - 1 Subtract 1 from both sides

y+1 -1< -1-1

y < -2

2) Now let's graph this solution on the number line:

Note that as it is y < -2 then we have an open circle since it does not include -2 within their possible solutions.
