Graphing Lines By Plotting Points Examples Page 1

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.

x	y = -½x – 2	(x, y)
	y = -½(0)– 2 y = 0 – 2 y = -2	(0, -2)
1	y = -½(1)– 2 y = -½ – 2 y = -2½	(1, -2½)
2	y = -½(2)– 2 y = -1 – 2 y = -3	(2, -3)

Now let's plot them and connect them:
