Question

x+3=0
how do you graph that?

y= -1
how would you graph that?

Answer 1

nevermind i figured out y= -1 but how would you graph x+3=0

Answer 2

y = x + 3
Pick values for x, solve for y

Example,
x = 0
y = x + 3
y = 0 + 3
y = 3
(0, 3)

x = -1
y = x + 3
y = -1 + 3
y = 2
(-1,2)

x = 1
y = x + 3
y = 1 + 3
y = 4
(1,4)

Picks more values for x as needed. Use these points to graph.
