Answer:
5 Units Long and (-10.5, 4)
Step-by-step explanation:
Length:
Using the Pythagorean theorem;
a:3 and b:4.
a^2=9 and b^2=16; 9+16=25
sqrt25=5. The length of the line is 5 units long
Midpoint:
Rise: 4, Run: 3; The slope is y=4/3x+b (b is irrelevant)
If we go half the distance of the line (½*3=1.5 and ½*4=2);
We would Rise 2 and Run 1.5 from Point E, and would end up at (-10.5, 4)
Here's image proof:
