We have points (-3, 4), (-1, 2), (4, -3) and (6,-5)

Let's verify it's a line by calculating the slopes between successive points.

Slope is change in y over change in x.

(2 - 4)/(-1 - -3) = -2/2 = -1

(-3 - 2)/(4 - -1) = -5/5 = -1

(-5 - -3)/(6 - 4) = -2/2 =-1

Yup.  We have a line of slope -1 through point (-1, 2)

y - 2 = -1(x - -1)

y  = -x - 1 + 2

y = -x + 1

That's the linear equation for the table.  

Answer:  Linear equation: y = -x + 1          slope = -1
