Me ! i will give what is the distance between point a (-1,3) and point b (-7,3)? a. 1 unit b. 3 units c. 6 units d. 8 units

You can use the distance formula:


To figure out what the distance between the points is. Our x1 is -1, and our y1 is 3. Our x2 is 7, and our y2 is -3. Then, we can just plug it in, and solve:


Simplify:


Simplify Further (S is the distance):


So, the answer is D, 8 units. If you want me to explain what I did, just tell me, I sure will! :) Anything still unclear?

The answer maybbe c

1.3 and 1 1/3 are both closest to 1. hope this ; )
