Graph the equation y = -½x – 2.
Again, it would probably be best to pick some values for x and solve for y, since y is already isolated.
Now let's plot them and connect them:
Graph the equation x + 3y = 7.
With all equations, it is really up you which variable to solve for, but for this problem it would be easiest to solve for x, since it doesn't have a coefficient.
Now, let's plug in some numbers for y and solve for x.
Since we picked values for y and solved for x, we must be careful to plot them in the correct order, x then y.
Graph the equation 2y = 6x.
Let's solve this one for y.
Now, let's plug in some numbers for x and solve for y.
Plot and connect.
