Answer:
The slope of the line is -1.
Step-by-step explanation:
You have to choose any 2 coordinates and put into the gradient formula. I will choose (0,2) and (2,0) :
[tex]m = \frac{y2 - y1}{x2 - x1} [/tex]
[tex]let \: (2,0) \: be \: (x1,y1) \\ let \: (0,2) \: be \: (x2,y2)[/tex]
[tex]m = \frac{2 - 0}{0 - 2} [/tex]
[tex]m = \frac{2}{ - 2} [/tex]
[tex]m = - 1[/tex]
