Answer 1

To find the slope of this line, we will prove that this line is a vertical line ( x1 = x2). Then, the slope for this is not defined, as we can see:

x1 = -2

y1 = -2

x2 = -2

y2 = 1

Then

$m=\frac{y_2-y_1}{x_2-x1}\Rightarrow m=\frac{1-(-2)}{-2_{}-(-2)}=\frac{1+2}{-2+2}=\frac{3}{0}$

Since the expression is m = 3/0, this is undefined. Then, the slope for this vertical line is undefined. Some authors say it is an infinity slope.
