Question

Which inequality is graphed on the number line

Answer 1

Answer:

2nd option: 3a-11≤7

Step-by-step explanation:

Step 1: The inequality on the number line is:

$a \leqslant 6$

Step 2: Take a look at the options. First we know that we want values of a which are less than 6 so we get rid of option 1 and 3.

Step 3: Since 6 is included in the inequality so we need to have a ≤ so 2nd option is correct.

QUICK NOTE: if we solve the inequality shown in the 2nd option we'll see it's gonna be a≤6

take a look:

$3a - 11 \leqslant 7 \\ 3a \leqslant 18 \\ a \leqslant 6$
