Answer:
slope = 0
Step-by-step explanation:
calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = (- 2, 4 ) and (x₂, y₂ ) = (3, 4 )
m =
=
=
= 0
For number 3, it is reciprocal
and for number 4, it is whole number
Answer:
x = -1
Step-by-step explanation:
to find axis of symmetry, use the following equation:
x = -b/2a
in this problem, a = 3, b = 6, c = -12
x = -6/2(3)
x = -6/6
x = -1
