Answer:
12 units
Step-by-step explanation:
B - A = (7, 8) - (-5, 8) = (7 -(-5), 8 -8) = (12, 0)
The distance is then ...
d = √(12² + 0²) = √12²
d = 12
_____
Of course, when you graph these points (actually or mentally), you can see that they are 12 units apart on the line y=8. You don't need to do any fancy calculation to discover the difference between -5 and 7.
You should use mathway it really helps with problems like this.
You’re answer here is the third one
5 is not a function because if you draw a vertical line then it touches twice which is not a function
6 is a function
7 is not a function because there are 2 of the same inputs
8 is a function because it passes the vertical line test
9 is not a function
10 is a function
Hopefully that helped!
(-2,-4) is the correct answer.
Hope this helps:)
