-3y=2x-7
what are you trying to find here @rabaca ?
graph the equation by plotting three points -3y=2x-7
Try putting numbers 1, 2 and 3 in place of the x to get y numbers. plot the points (x,y) example (0,7/3)
did you put this into y = mx + b format by dividing by -3 (writing /-3 next to each term, then simplifying) ?
-3y/-3=2x/-3-7/-3
yes, now simplify
1y=-1.5x-7
1y is ok \[ \frac{2x}{-3} \text{ is the same as } \frac{2}{-3} x \] -2/3 is not -1.5 (-3/2) alos -7/-3 is 7/3 not 7 try again
1y=-3/2x+7/3
you mean \[ y = \frac{-2}{3} x + \frac{7}{3} \] how did you get -3/2 for the slope ?? you have -3y/-3=2x/-3-7/-3 that is 2 divided by -3 for the slope
to get a nice y, try x=2 then use the slope = change in y divided by change in x change in y is -2 and change in x is 3 that means add 3 to x and -2 to y to get the next point
2,1
then use the slope = change in y divided by change in x change in y is -2 and change in x is 3 that means add 3 to x and -2 to y to get the next point
5,-1
ok, now one more point
8,-3
yes, those are good. Good luck. I have got to sign off.
thank you
