A.
y + 3 ≥ –1

B.
y + 3 > –1

C.
y + 3 ≤ –1

D.
y + 3 < –1

Answer 1

from the number line you know that all possible y values are any values below -4, but not including -4, which is represented by the unfilled 0 above -4

so you want to re arrange these given equations to see which one gives an inequality of less than -4

Answer 2

learn this :
An open circle means there is no equal sign.
A closed circle means there is.
Shading to the right means greater then
Shading to the left means less then.
So you can tell just by looking at the number line, that you will need the equation with the solution of : y < -4
do you see how I got that ?

Answer 3

and since we know there is no equal sign (because of the open circle), that eliminates A and C

Answer 4

so i would try to solve the two equations that are left to find which one is less than -4

Answer 5

yes ...give it a try

Answer 6

so i would subtract 3 from both sides

Answer 7

yes....on both of the remaining equations

Answer 8

because we want y by itself

Answer 9

i got d

Answer 10

correct :) way to go

Answer 11

you deserve a medal for that :)
