The slope of the line is:
m = ∆y / ∆x
In this case:
m = ( y2 - y1 ) / ( x2 - x1 )
m = [ - 0.3 - ( - 0 .35 ) ] / [ - 1 - ( - 2 ) ]
m = ( - 0.3 + 0 .35 ) / ( - 1 + 2 )
m = 0.05 / 1
m = 0.05
m = ( y3 - y2 ) / ( x3 - x2 )
m = [ - 0.25 - ( - 0 .3 ) ] / [ 0 - ( - 1 ) ]
m = ( - 0.25 + 0 .3 ) / ( 0 + 1 )
m = 0.05 / 1
m = 0.05
m = ( y4 - y3 ) / ( x4 - x3 )
m = [ - 0.2 - ( - 0 .25 ) ] / ( 1 - 0 )
m = ( - 0.2 + 0 .25 ) / 1
m = 0.05 / 1
m = 0.05
m = ( y5 - y4 ) / ( x5 - x4 )
m = [ - 0.15 - ( - 0 .2 ) ] / ( 2 - 1 )
m = ( - 0.15 + 0 .2 ) / 1
m = 0.05 / 1
m = 0.05
