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!

Step-by-step explanation:
2.) 7a^2 + 50a + 7 = 7a^2 + a + 49a + 7 = a(7a + 1) + 7(7a + 1) = (a + 7)(7a + 1)
3.) 3x^2 + 11x - 20 = 3x^2 - 4x + 15x - 20 = x(3x - 4) + 5(3x - 4) = (x + 5)(3x - 4)
4.) x^2 + 7x - 18 = x^2 - 2x + 9x - 18 = x(x - 2) + 9(x - 2) = (x + 9)(x - 2)
