Giancarlo buys granola. The graph shows the relationship between the weight and the cost of the granola. Determine whether each statement is true or false. The point (8, 24) means that 8 pounds of granola costs $24. True or False

The point (1, 3) means that the unit rate is $3 per pound of granola. True or False

The point (4, 12) means that it costs $4 for 12 pounds of granola. True or False

Since the line passes through (1, 3), 3 is the constant of proportionality. True or False

The graph is not a proportional relationship. True or False

the answer is

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.
