Answer:
- DF = √(m²+n²)
- slope = -n/m
- midpoint = (m/2, n/2)
Explanation:
The distance formula or the Pythagorean theorem will tell you the length of DF:
DF = √((m -0)² +(0 -n)²)
DF = √(m² +n²)
The slope can be found from the slope formula or by looking at rise/run.
slope = rise/run
slope = -n/m
The midpoint is the average of the end points:
midpoint = ((0, n) +(m, 0))/2
midpoint = (m/2, n/2)
