Reminder: You can't just plot one dot, i meant do that like two times, then draw a line through it. This way you can shown the point of intersection.
1st Problem: Plot a dot at -4 on the y-axis, then go down two and right one and plot another dot. Then for the second equation, add 4 to both sides. then you will come out with y= -4x+2. then with this, go ahead and plot a dot at positive 2, and go down four and to the right one. if you are trying to find the point of intersection, then it would be (2, -8).
2nd Problem: Plot a dot at -2 on the y-axis, hen go down three, and to the right 2 and plot a dot. Then for the second equation, plot a dot at positive 3, and go down 1 and to the right 4.
3rd Problem: Plot a dot on the y-axis at -5, then you are going to draw a straight line going across. The for the second equation, plot a dot at positive 1 on the y-axis, then go down three, to the right one.
