Answer:
Look Below
Explanation:
The form for this equation is y = mx + b with m being the slope and b being the y intercept, so -1 is the slope and 3 is the y intercept:
With that we can just use different numbers to make the equation true for different points:
Ex: (1, 2) - - > 2 = -(1) + 3
(2, 1) - - > 1 = -(2) + 3
So now that you have filled points you can graph it
Result:
