Let y directly proportional to X
thus y = CX
where c is proportionality constant
given c= 9
thus y = 9x
This equation has one solution which is -1.5
3x+7=-3x-2
+2. +2
3x+9=-3x
-3x. -3x
9= -6x
/-6. /-6
X= -1.5
Answer:
- 1.375
Step-by-step explanation:
Each dot is worth -1/8 of a unit when moving left.
So the coordinates of the dark dot are - 1 and - 3/8
or - 1.375 . The word coordinates (plural) bothers me. It all depends on how you have been asked to represent these points. Another possibility is (-1.375,0). You have to choose from the examples you have been given. I wouldn't do that because you have not been given and xy graph.
