Answer:
-
and
Explanation:
Calculate the slope m using the slope formula
m =
with (x₁, y₁ ) = S(12, 9) and (x₂, y₂ ) = T(21, 3)
=
=
= -
Repeat with
(x₁, y₁ ) = S'(4, 3) and (x₂, y₂ ) = T'(7, 1)
=
= -
-----------------------------------------------------------
(x₁, y₁ ) = R(24, 18) and (x₂, y₂ ) = S(12, 9)
=
=
=
Repeat with
(x₁, y₁ ) = R'(8, 6) and (x₂, y₂ ) = S'(4, 3)
=
=
=
