Answer:
The desired distance is 15 units.
Explanation:
Note how x increases from 1 to 10 and y from 0 to 12 at the same time.
Using the Pythagorean Theorem, we find that the distance between the two points is the length of the hypotenuse, which is
d = √[ (10 - 1)^2 + (12 - 0)^2 ], or d = √ [81 + 144] = 225 = +15
The desired distance is 15 units.
