Answer:
Hello, I am also working on graphs at the moment!
Explanation:
it is -8 units. If you place the points on a graph, you can see that it is going from point (4,5) and (4,-3) (the points given) now all you do is count the units between them.
Thus, the distance between the two points is, -8 units. Hope this helps! let me know if its right pls :) thx <3 (can also be written as- (0,-8) because its decreasing)
