Is there away to find "fractions" or if not called fractions not sure what the correct word is I believe I have found out that if it's 3/2 it's found still between 1 and 2 ? just like if it was 5/2 it would still be the same I think as the bottom number is still 2 If that's wrong sorry. yet for this problem, and hopefully future ones is there away to know where the "fraction" is found on a graph?

Points (0, 2) and (3, 2) are on the graph. Can you see why?

In answer to your question, yes there is a good way. Converting the fractions to mixed fractions will help a lot. For example, $\dfrac{3}{2} = 1\dfrac{1}{2}$, so you can then infer that it lies halfway between 1 and 2. Similarly, $\dfrac{5}{2} = 2\dfrac{1}{2}$, so you can infer that it lies halfway between 2 and 3.

y = 4/3x + c 3y = 4x + 3c fill in (0,2) 6 = 3c c = 2 y =4/3x  2

Senior Member Joined: Feb 2016 From: seattle Posts: 371 Thanks: 10  I think I see why 0,2 would be as there is only 2 so I guess that means x is zero. I don't see how you got (3,2) from the 4/3 I am guessing? unless for some reason we are ignoring the 4? thanks for the help.

start at the yintercept, (0,2) ... do the rise/run to find at least one more point of the line. Connect.

Then M is where I go from after finding my y. I know that's not correct but It's how my memory is working. Or Maybe it's better to say My B is my starting point, then M is where I go from finding my starting point?

you just have to draw a line between the points {x=o and y=2} and{x=3 and y=2} you can do that with a lineal what do you don't understand?
