(-3, 1)
4x-9y=-21
+-4x-3y=9
-12y= -12
y=1
4x- 9(1)= -21
4x-9=-21
+9 +9
4x= -12
x=-3
Answa line of symmetry will connect a vertex and a midpoint of an opposite side
it has 7-fold symmetry.
Step-by-step explanation:
A line of symmetry is a line that we can use to "fold" a figure in half. In order to do this, we will "fold" the figure from a vertex to the middle of the side opposite the vertex. Since there are 7 vertices, there will be 7 lines of reflection. i looked it up so i hope this helps you can thank

Answer:
the difinition of addition is adding two things together
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
Calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = (4, 9) and (x₂, y₂ ) = (12, 20)
m = 
= 
→ C
