Ok

so this is what we got to do.

a) the y intercept is 4.95 because it is the base or initial cost and if you talk  no minutes you still pay that amount.

b) plot a point at 4.95 and then go 0.05 up and 1 sideways.so you have your graph.

c)y= 0.05m+4.95
  y= 0.05(140) +4.95
  y= 7+4.95
  y= 11.95

the cost for 140 minutes is $ 11.95.

did this help??

CHEERS
