Answer: Choice B)
This is the same as saying y/x = 2/3
Or I suppose you could say "y over x = two-thirds".
===============================================
Step-by-step explanation:
Recall that slope is rise over run
slope = rise/run
The rise being the change in y, while the run is the change in x.
So we could informally think of it as slope = y/x
-----------
Since we're told that it "has a rise of 2 and run of 3", this means slope = 2/3.
The slope is both y/x and also 2/3.
Equating the two expressions leads us to y/x = 2/3. This is why choice B is the final answer.
-----------
Side notes:
- This trick only works when the line goes through the origin (0,0)
- To rephrase the last bullet point, the line must have y intercept 0.
- If you multiplied both sides by x, then you get y = (2/3)x
