I have to send it through the computer. L1) x - 2y = 8 L2) x + y = -1 For L1, let y=0 and solve for x x-2(0)=8 x-0=8 x=8 Plot (8,0) Now let x=0 and solve for y: 0-2y=8 -2y/-2=8/-2 y=-4 plot (0,-4) Connect the points and you have this line. For L2), let y=0 and solve for x x+0=-1 x=-1 Plot (-1,0) Let x=0 and solve for y 0+y=-1 y=-1 Plot (0,-1) Connect the points and you have a second line: They intercect at (2,-3) Happy Calculating, Lyn!!!
