the formula of a slope:
from a table we have
the slope of f(x) is -1.
the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.
-1 < 0answer: the function g(x) has the greatest slope.
answer: the paragraph proof is mentioned below.
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)
therefore, xz⊥wy where wz=zy
⇒zx is a perpendicular bisector of wy.
2 is to go somewhat to the top right of a because it is squared
