Quadratic Equations/ Linear Equations
A quadratic equation is defined as an equation in which one or more of the terms is squared but raised to no higher power.
A linear equation is defined as an equation in which the highest power is 1
Linear - quadratic system
This familiar linear- quadratic system, where only one variable is squared in the quadratic, will be the graph of a parabola and a straight line. When a parabola and a straight line are graphed on the same set of axes, three situations are possible.
Solve this problem manually (without graphing calculator):
y = x2 - 4x - 2 y = x - 2
Solve this problem using a graphing calculator:
y = x2 + x - 1 y = -2x + 1
