B) It is a line joining the points whose x- and y-coordinates add up to 6.

C) It is a line which intersects the x-axis at (3, 3).

D) It is a line which intersects the y-axis at (3, 3).

its c or d   take a lucky guess my dude

correct answer:

b.(19,-2)

b. 153 students do not participate in sports and seventy-five 12th graders were surveyed

answer:   the paragraph proof is mentioned below.

step-by-step explanation:

given: in a δxwy where

such that, ∠wzx ≅ ∠yzx and zw≅zy

we have to prove that: segment zx is a perpendicular bisector of segment wy.

prove: since, zw≅zy ⇒ ∠wzy is a supplementary angle.

then, ∠wzy= 180°

⇒∠wzx + ∠yzx = 180° ( because xz divides ∠wzy into two parts)

but, ∠wzx ≅ ∠yzx ( given)

⇒∠wzy+∠wzy=180° ( by substitution)

⇒2∠wzy=180°

⇒∠wzy=90°

⇒∠wzy=∠yzx =90°

therefore, xz⊥wy where wz=zy

⇒zx is a perpendicular bisector of wy.
