Answer:
y = -3x + 3
Step-by-step explanation:
Plug the y and x values from the point (-1, 6) along with the slope of -3 into the slope intercept formula: y = mx + b to get 6 = (-3)(-1) + b
Solve for b: 6 = 3 + b
3 = b
Now put the slope and the y intercept that you just found (b) into the equation to get the final answer.
