A solution for a system of equations is an ordered pair (x , y) thatmust satisfy both equations.
The Left Side = Right Side, for both equations.
They are A.K.A. the point(s) of interesection on a graph.

Number of Solutions
Both systems of Linear-Quadratic or Quadratic-Quadraticequations could have 0, 1, or 2 solutions.
Unlike when we solve radical or rational equations, there will be noextraneous roots or non-permissable values.

Linear-Quadratic Equations Solved Graphically
In order to graph functions to find their solution(s), keep in mindtechniques that you have learned throughout this course and inprevious years.
The simplest way to graph a linear function is by using the slopey-intercept form.
y = ax + b, where a = slope, b = y-intercept

Linear-Quadratic Equations Solved Graphically
The simplest way to graph a quadratic function is by using thevertex-form method.
y = a(x − p)2 + q, where a = stretch factor, (p, q) = vertex
If our function is written in Standard-Form, we must COMPLETETHE SQUARE to convert it to Vertex-Form.

Number of Solutions to a System of EquationsSolving Systems Graphically
Substitute x = 6 into one ofthe original equations to find y:
x2 − 2x − y = 10
62 − 2(6) − y = 10
36 − 12 − y = 10
−y = −14
y = 14Therefore, the solution is (6, 14).

Using SubstitutionUsing Elimination
It is your choice which method to use when solve any system ofequations.
It is my suggestion that you become familiar with both, but pick amethod you prefer.
For both examples, we were able to factor or use order ofoperations to solve for x. But if neither of these is possible, andthe equation is quadratic, remember that the quadratic formula isnecessary.

Main File - LaTeX. Second File - Maple
Grading Scheme - LaTeX = 40 marks, Maple = 10 marks
Go Beyond - I decided to use LaTex Extra content, specificallycreating a presentation. I decided to use the beamer documentclass to create this presentation in order to organize theinformation in a different format. I also found how to creategraphs in Maple with multiple functions.
Description - Due to a large amount of curriculum, my Grade 11Pre-Calculus students will complete one unit of independent study,where this presentation is their notes. The Unit is on Systems ofEquations (linear and quadratic).
