Answer:
The slope is 
Step-by-step explanation:
The slope of the line passing through
and
is given by the formula;

The given line contains;the points (2, -6) and (-3, 1).



The slope is 
Answer:
4=symmetrical; 4 lines 5=not symmetrical 6=symetrical; 1 line 7=symetrical; 5 lines
8: Isos. trap.=1
Rectangle=2 lines
Square= 8 lines
Rhombus=4 lines
Parallelogram= 0 lines
9 a: A regular pentagon has 5 lines of symetry
9b: a regular hexigon has 12 lines if symetry.
The length of the rectangle would be 18 centimeters
Use the given equation and solve for C.
F = 9C/5 + 32
F - 32 = 9C/5
5(F-32) = 9C
C = 5(F-32)/9
