I REALLY NEED HELP PLZ!!!! PICTURE DOWN BELOW!

the graph represents the last five years of computer hard drive production for Quality hard disks.

Part A

the variable T represents the time (in years). List the ordered pairs for t = 1 and t= 2

Part B

write an equation to represent the relationship between the time, t, and the number of hard disk produced ,p.

Part A:
To do this you have to find where t=1 and where 1=2. Then you have to go up the y axis (the vertical axis) until you hit a dot. For example, t=1, from t=1 you go up until you reach the dot which is located a 1,200. Then the ordered pair is (x [number of hard disks produced] ,y [time]) so it would be (1,1200)
Part B:
To do this you have to find a pattern between the x and the y coordinates. Easiest way is to divide the y by the x and see fi that works for all of the points.  Example: (1,1200) 1200/1=1200 (2,2400) 2400/2=1200. Bingo! The relationship is multiple the x (t) coordinate by 1200. The equation would look like this: 1200t=p
