To find slope of two points connected by a line, you have to use the formula

divided by

. Do six minus one or one minus six and find the absolute value (5). Now divide that by -4-(-5) or -5-(-4) and find the absolute value (1). 5/1. The slope is five.
In scientific notation the answer would be 6.4 times 10^-3

I hope this helps!
The question isn't very clear to me but i'll try it out.
B-2=1
B=1+2
B=3
HOPE I HELPED!!!
You cannot use the Pythagorean Theorem to find the side of a equilateral triangle because you can only use it to find the side of a right triangle. The Pythaggorean Theorem only works for right triangles.
