how do you graph 4x-5y=12

OpenStudy (dumbcow):

plug in x=0 to get y_intercept y = -12/5 plug in y=0 to get x_intercept x = 3

dumbcow ... yOu are right ... also we have equation of first degree with two variables .. first degree means that the drawing is a straight line , two variables means the drawing area in two axis for example x and y . second degree is meaning curve . so from this idea .. my friend Dumbcow ... took two points and you are need just to put your ruler and do it !

Isolate your Y term to to the left by subtracting your X term from both sides.\[-5y=4x+12\] Now, divide both sides coefficient of your Y term (-5 in this case).\[y=4/5*x-12/5\] Since your Y-intercept (-12/5) is part of the equation, it is good to use as one of your points. \[(0,-12/5)\] If you substitute zero in for Y, you'll get \[x=3\] That gives you another good ordered pair or point to use.\[(3,0)\] Please let me know whether or not you can view the attached picture file I've attached to show how to graph this equation. Thanks.
