How do you graph y+3=0? on a graph like this

So
y+3=0
subtract 3
y=-3
so since x is not involved,
look at the y axis (vertical) and go up -3 units (go down 3 units)
draw a horizontal line throug that point that is 3 units down
it has to be paralell to the x axis and never cross it

The answer is A) equation because it has an equal sign along with an algebraic equation :)

an inequality would have a greater than (or equal to) or lesser than (or equal to) sign

absolute value would have the side bars by the number

expression wouldn’t have an equal sign
