Below represents the proof that the quadrilateral QRST is a parallelogram
<h3>How to prove that QRST is a parallelogram?</h3>The coordinates are given as:
Q = (-1,-1)
R = (2,9)
S = (-4,5)
T = (-7,-5)
Calculate the length of each side using:
So, we have:
The above computations show that opposite sides are equal.
Next, we determine the slope of each side using:
So, we have:
The above computations show that opposite sides are parallel, because they have equal slope
Hence, the quadrilateral QRST is a parallelogram

Answer:
Step-by-step explanation:
We want to prove algebraically that:
is a parabola.
We use the relations
and
Before we substitute, let us rewrite the equation to get:
Or
Expand :
We now substitute to get:
This means that:
Square:
Expand:
This is a parabola (0,2.5) and turns upside down.
