The cost to belong to a gym is $25 each month and a one time fee of $100 to join.
what is the slope and the y-intercept in this situation.
a)
the slope is the the one time fee to join. the y-intercept is the cost of the gym each month.
b) the slope is the cost of the gym each month. the y-intercept is the one time fee to join.
c) the slope is the one time fee to join. the y-intercept can not be determine in this problem.
d) the slope can not be determined in this problem. the y-intercept is the one time fee to join.

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.
