Pls help ;-; Student #2:

4x + 1 ≤ -4
x + 1 ≤ -1
x ≤ -2


Solved the inequality incorrectly and graphed their solution incorrectly.
Solved the inequality correctly but graphed their solution incorrectly.

Solved the inequality correctly and graphed their solution correctly.

Answer 1

Explanation:

4x+1 < -4

-1 -1

--------------

4x < -5

`x \leqslant ( - 5)/(4)`

-5/4 is not 2, so both of them are wrong (1 is right choice)

Answer 2

solved the solution incorrectly and graphic their solution correctly.

Explanation:

this is because if 4x + 1<= -4

the next step will be to subtract 1 from both sides.

BUT if their solution is x<= 2, they objectively graphed it correctly
