Of the three linear functions represented below, which has the greatest rate of change?
a. a number,y, is two less than twice a number,x.
b. 3y-4x=3
c.(2,2) (0,-3) (graphed)
c has the greatest rate of change, which can be determined by the slope in y=mx+b
a. slope=2 y=2x-2
b. slope=4/3 y=(4/3)x+1
c. slope=2.5
