What fraction is located at point a on the number line

1 1/2

Step-by-step explanation:

Since there are 4 tics between 1 and 2 (including the tic on 2), we can assume that the number line is split into 1/4 (quarters). Therefore, each tic is 1/4 higher than the last. The tic after 1 is 1 1/4, the next is 1 2/4, the next is 1 3/4, and the last shown is 1 4/4 (which is rewritten as 2). The tic marked is at 1 2/4, which can be simplified to 1 1/2.

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1
