Find the slope of the line through the points

(-4,4) and (0,-4).

2 answers

slope, call it m, is

m = (Y2-Y1)/(X2-X1)

m = (-4 - 4) / (0 - -4)

= -8/4

= -2
NOW SKETCH A GRAPH AND LOOK AT THOSE POINTS AND A LINE FROM THE FIRST TO THE SECOND. NEVER do one of these problems with sketching a quick graph off to the side.
