Tomas is planning out a rail trail using a map with a marked grid. The head of the trail, which has an information kiosk, is located at (3, 0). He moves 1 unit east and 3 units north and places a pin at (4, 3) to represent the location of another information kiosk. He continues placing pins so that each pin is 1 unit east and 3 units north in relation to the previous pin. Which of the following points will have pins? Select all that apply.

The points that will have pins can be determined by applying the same pattern of moving 1 unit east and 3 units north from the previous pin.

Starting from (4, 3), we can determine the following points:

(4+1, 3+3) = (5, 6)
(5+1, 6+3) = (6, 9)
(6+1, 9+3) = (7, 12)
(7+1, 12+3) = (8, 15)
(8+1, 15+3) = (9, 18)

So, the points (5, 6), (6, 9), (7, 12), (8, 15), and (9, 18) will have pins.
6,9 is,nt on there tho its only 6,8
