The slope intercept form of the equation is given by:

y = mx + c

where +m+=+%28y2+-+y1%29%2F%28x2+-+x1%29

We find the slopes of the given set of points.

The slope of the first set of point is -1

so 3 = (-1)(-1) + c

==> 3 - 1 = c

==> c = 2

Hence, the equation is:

y = -x + 2

thus the solution.

============================================================================
2) The slope of thsi equation is 0

Therefore -3 = (0)(2) + c

==> c = -2

y = -2

is the equation in the slope intercept form.


Thus the solution.
