Plz hurry i don't wanna miss this she said it's going to count 20% on this one instead and i'm not good at math but don't want my grade to drop.

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!
