(Y2-y1)/(x2-x1) (-14-18)/(-9-20) -32/-29 =32/29
the slope is 32/29
the slope = ( -14 - 18 ) / ( -9 -20 ) = (-32)/(-29) = 32/29.
The slope of the line through the points (20, 18) and (-9, -14) is 29 32 . This indicates that the line rises 32 units for every 29 units it runs horizontally. A positive slope means that the line moves upward as you go from left to right.
