(4,2) graph the vertex

To plot (4,2) start at the origin (0,0) and move right 4 units and up 2 units (4,2)

d = 6t

Step-by-step explanation:

Firstly, lets change the 2 hours and 30 minutes to 2.5 hours, you could devide the time in minutes by 60 to get that number 2[hours]+()[minutes to hours] = 2.5Hours. Anyway, John ran 15 miles in 2.5 hours which means he ran (15÷2.5) in one hour which is equal to 6miles per hour. That means if you multiply the hours he ran by 6 you will get the miles he ran. So the answer would be:

d = 6t
