answer:

I think the answer is B. Hope it helps

Step-by-step explanation:

Let the point (-4, 2) be F (fountain).  The point (0, 2) will be B (bench) and the point (0, 5) will be S (slide).
A) the distance from F to B would be 4.  We can use the distance formula, but for a horizontal distance such as this it's easier just to count.  The y-coordinates don't change, and the x-coordinates are 4 units apart.
The distance from B to S would be 3.  It is a vertical distance; the x-coordinates don't change, and the y-coordinates are 3 units apart.
B) These 3 points form a right triangle.  The slope from F to B is given by
m=(2-2)/(-4-0)=0/-4=0.  The slope from B to S is given by
m=(5-2)/(0-0)=undefined.  These are negative reciprocals of each other.
