 Question 22580: How Do I Graph These Equations? 3x+y=5 -2x+3y=4 Found 2 solutions by wuwei96815, sgt_spike:Answer by wuwei96815(245)   (Show Source): You can put this solution on YOUR website!The easiest way to graph an equation is to find the x and y intercepts. You only need two points to graph a linear equation. 3x+y=5 Let x=0 3(0) + y = 5 y=5 You now have the point (0,5) which is called the y-intercept. 3x+y=5 Let y=0 3x + (0) = 5 x=5/3 You now have the point (5/3,0) which is called the x-intercept. Plot the two points and draw a straight line. Any questions? Answer by sgt_spike(2)   (Show Source): You can put this solution on YOUR website!First solve for y. To do this multiply 3x+y=5 by -3 on both sides of the equation. (-3)3x+y=5(-3) -9x-3y=-15 subtract this equation from the other equation -9x-3y=-15 -2x+3y=4 -11x=-11 Divide by -11 on both sides to get x=1 substitute the 1 in the equation -2x+3y=4 -2(1)+3y=4 -2+3y=4 Now solve for y 2-2+3y=4+2 3y=6 y=2 start point (1,2) Thats how to solve it. DOn't know how to graph it. Sorry
