Answer:
1 is y=-1/3x. 3 is y=-3/2x. 5 is y=5/3x
Explanation:
Simply count the vertical lengths. Meaning count up or down how ever many. That is your top number. Then count your horizontal lengths, meaning left or right, this your bottom number of the slope. So if point A is at (-1,-1) in example 1, then count down 1, and right 3 spaces. Because you go down, the slope is negative, and you went down 1, so the top number is 1, you went right 3 units, so the bottom number is 3.
