@Michele_LainoY-intercept of (0, –1), starts down on the left, gets closer to y = –3 on the right
	Y-intercept of (0, –1), starts up on the left, gets closer to y = –3 on the right
	Y-intercept of (0, 1), starts up on the left, gets closer to y = –3 on the right
	Y-intercept of (0, 1), starts down on the left, gets closer to y = –3 on the right
