Hello!
To find the slope of this equation, you need to get the variable "x" by itself. Remember to use SADMEP when solving algebraic equations. : )
2x + 2 = 0 (subtract 2 from both sides)
2x = -2 (divide 2 from both sides)
x = -1
x = -1 is an example of a vertical line, which has an undefined slope.
Therefore, the slope of the equation given is undefined.
