y=-3x+2

x -3 -2 -1 0 1 2 3
y 11 8 5 2 -1 -4 -7

Two question-
Where is the slop in the equation?
How can you tell the slope in the table

The slope of the equation would be -3

You can find the slope of an equation by using the equation, y=mx+b, m being the slope and b being your y-intercept.

The slope of an equation is also the change in y over the change in x. So looking at that table you have there, from 11 to 8 is -3 in your y, and from -3 to -2 is 1 in your x. So -3/1 = -3
