point b: (3,-5)
reasoning: ab is 5 units long, and point a is at -2. -2 + 5 = 3, so b’s x-coordinate is 3. point b is at y-coordinate -5 because it is at the same y-coordinate as point a.
point c: (3,5)
reasoning: point b is at (3,-5) and is 10 units away from point c. they appear to be at the same x-coordinate (3), so point c’s y-coordinate must be 10 units higher than point b. point b’a y-coordinate is -5, so -5 + 10 is 5. this makes point c (3,5).
point d: cannot he found with given information.
reasoning: though we can tell point d is on the y axis, making its x-coordinate 0, we cannot determine its y-coordinate. my best guess would be (0,-1) but there is no proof that this is true.
hope this helps! :)
