3x - 2y = -1Just so you know, this equation is of a line on a graph. It is in standard form.Ax+By=C, A and B cannot equal zero and A is greater than zero.A=3B=-2C=-1 As need coordinates for x and y.Let's make this easy, and begin with x=0[(3)(0)]-[2y]=-1-2y=-1Let's divide both sides by -2 to isolate y...(-2y)/-2=-1/-2y=1/2(0,1/2) y=03x - 2y = -1[3x]-[(2)(0)]=-13x=-1(3x)/3=-1/3x=-1/3(-1/3,0) For the third, how about x=1...3x - 2y = -1[(3)(1)]-2y=-13-2y=-1Let's subtract 3 from both sides...-3+3-2y=-1-3-2y=-4y=2(1,2)
