1a) 0.25m + c
1b) 1st picture
1c) 0.50m + c2
2a) y = 75h + c
2b) 750 - 100 = 650
650 / 75 = 8.667
8 hours and 40 minutes
3a) (32, 14.10) and (420, 33.50)
3b) y = 0.05m + 12.5
3c) It represents the relationship of the minutes to the total cost of the phone bill.
4a) (2, 127) and (3, 69)
4b) y = -58t + d
4c) The slope is negative, because the distance decreases the more hours Miguel drives.
4d) -58 * 0 + 243.
-58 * 1 + 243 = 185
Miguel started 243 miles away from NYC.
Try to use Excel for future graphing. You can add a trendline, which gives you the option of show the equation also.
Hope this helps!
