Answer:
Since the points form a triangle, you can use Pythagorean theorem to solve this.
Side A is 3 Units, and side B is 6. The letters do not matter when corresponding them to the sides.
So Pyth Theorem = a^2 + b^2 = c^2
And c^2 is the distance we must find
So a^2 = 9
b^2 = 36
So 36 + 9 = 45
To find C, you must root c^2
So sqrt of 45 is 6.7
The distance between points (3,7) and (-3,4) is 6.7 units.
