I'm too lazy to do the rest, just pay attention in class next time
X + 3 = 0 is not a function because it is a vertical line.
A vertical line has undefined slope because all points the line have the same x-coordinate.
A function is a relation in which no two ordered pairs have the same first component (x-values or input) and different second components (y-values or output).
Remember that a function can only take on one output for each input. Since a vertical line has the same x-coordinates for all values of y-coordinates, then it means that it is not a function.

Answer:
x = 6
Step-by-step explanation:
11 = 1/2x + 8
-> Move 8 to left side
11 - 8 = 1/2x
3 = 1/2x
->We can switch sides so 1/2x is on the left and 3 is on the right
1/2x = 3
x = 3 x 2/1
x = 6
Answer:
-1/6
Step-by-step explanation:
-1.5-(-0.5)
over
3-(-3)
slope= -1/6
Answer:
x + 2y - 18 =0
y = x - 3 is x = 3
