Answer:
A) Graph an quadratic equation for a parabola (x being to the power of 2), and a linear equation. Examples would be y=x² and y=x.
B) Parabolas that share the same vertex can simply have another transformation done to them. For example: y= 5x² and y=3x².
C) A line that would pass through these would be any linear graph WITHOUT a 'b' value, so a y intercept of 0. An example would be y=5x.
This claim is proven by building a bijection by following a diagonal procedure.
Imagine you have an infinite matrix, whose coefficient are all possible fractions:
Now, count them "diagonally": this is how we map every natural number, using the same positions:
