If lines joined each given point on the graph to the origin, which points would be on lines that represent a unit rate less than the one represented on the table? X Y
13 21
26 42
39 63

if you're trying to figure out how much each ounce cost it would be 0.20

cents each ounce

can i see a photo of the question so i can you?

  or  

sin y = 7/q

7 is the opposite side length, q is the hypotenuse

tan y = 7/r

7 is the opposite side length, r is the adjacent side length

using sohcahtoa ^^^^

cos y = adjacent/hypotenuse

cos y = r/q
