Answer:
10 units
Step-by-step explanation:
to find the distance between two points you will need to use the distance formula:
the x1 refers to the x coordinate in the first bracket, the x2 refers to the x coordinate in the second bracket, etc.
insert the coordinates into the equation:
a double negative equals a positive
insert this equation into your calculator:
= 10
∴ the distance between the points (1,1) and (7,-7) are 10 units
