Linear Equations
The equation y = mx + b is considered to be written in this form.
What is Slope-Intercept Form?
A relation is a function if this occurs.

or
What is passes the vertical line test?
In the standard form of a quadratic equation
y = ax2+bx +c, the c represents this important point on the graph.
What is the y-intercept?
Writing a quadratic equation in factored form helps to find these important points on a parabola.
What are the x-intercepts or zeros?
i243
What is -i ?
It is the slope of the line that passes through the points (7, 5) and (-2, -3).
What is 8/9?
What are a horizontal translation to the right 4 units and a vertical translation up 7 units?
When given the standard form of a quadratic equation, this equation can be used to find the equation for the axis of symmetry.
What is x = -b/2a ?
The factored form of the quadratic equation
f(x) = x2 - 5x + 6 would like like this.
What is f(x) = (x-3)(x-2) ?
(3 - i) + (6 + 3i)
What is 9 + 2i ?
The slopes of two perpendicular lines will be related in this way.
What are opposite reciprocals?
As x approaches infinity, f(x) approaches infinity, and as x approaches negative infinity, f(x) approaches negative infinity is a way to describe this key feature of a function.
What is the end behavior?
What is the quadratic term?
The zeros of a quadratic function are -3 and 6, the equation written in factored form would look like this.
What is f(x) = (x + 3)(x - 6) ?
(4 - 2i) - (2 - 4i)
What is 2 + 2i ?
A line passes through the point (-1, 9) and is parallel to the the graph of the equation y = 3x - 7, will have this equation.
What is y = 3x + 12?
Functions will change from increasing to decreasing or from decreasing to increasing at these important points on a graph.
What are relative maximums or relative minimums?
or
What are extrema?
A parabola with minimum of (3, 5), will have a range of this.
What is y is greater than or equal to 5 ?
What are -12 and 8 ?
(5 - 2i)(2 + 4i)
A line passes through the point (4, 5) and is perpendicular to the graph of the equation
y = - 4x + 7 will have this equation.
What is y = 1/4 x +4 ?
A function will change from positive to negative or negative to positive at these important points on a graph.
