Okay so I have to plot points, which is rather easy to do...
So I go to mathway.com and put in
2x3y=7 , right? Then I click the option to find three ordered pairs.
But then I got things like (0,7/3) , (1,5/3), and (2,1)
Well the last one was easy to plot. But the first two .... Errr.
I'm on a program doing a test and it'll only let me plot whole numbers like (2,1)
If someone could help me or help explain how to plot those, or something that'd be great !

Best ResponseYou've already chosen the best response.0if you put the equation into y = mx + b form you get \[ y= \frac{2}{3} x + \frac{7}{3} \] as you noticed (2,1) works: y = (2/3)*2 + 7/3 = 4/3 +7/3 = 3/3 = 1 next, notice the slope is 2/3 change in y is 2 , change in x is 3 that means if you add 3 to the x , the y goes down by 2 (i.e. add 2)

Best ResponseYou've already chosen the best response.0once you find a nice point such as (2,1) you can add 3 to the x and 2 to the y to get another nice point
