Slope formula: [tex] \frac{y_2 - y_1}{x_2 - x_1} [/tex]
First, you would need to plug the coordinates into the slope formula.
[tex] \frac{4 - 6}{0 - (-2)} [/tex]
Now, all you would need to do is solve and simplify it.
[tex] \frac{4 - 6}{0 - (-2)} [/tex] = [tex] \frac{-2}{2} [/tex] = -1
The slope would be -1.
I hope this helps!
