(-1,1),y=x-4

The given equation is y = x - 4. The point (-1, 1) is also given.

To check if the point (-1, 1) satisfies the equation, we need to substitute the x and y coordinates of the point into the equation and see if it is true.

Let's substitute x = -1 and y = 1 into the equation:

1 = (-1) - 4

Simplifying this equation:

1 = -1 - 4

Rearranging the terms:

1 = -5

Since -5 is not equal to 1, the equation is not satisfied by the point (-1, 1).
