Relations
An image of two circles that shows the relationship between the input and output values
What is a mapping diagram?
The horizontal axis on a coordinate plane.
What is the x-axis?
The y-value of an ordered pair, represents the vertical placement of the point.
What is y-coordinate?
The x-values in a function
What is the domain?
Scanning your pencil left to right and identifying the x-values in which you are "touching" the graph.
What is domain?
Relationships between two variables where their ratios are equivalent
What is a proportional relationship?
The vertical axis on a coordinate plane.
What is a y-axis?

What is x-coordinate?
The y values in a function.
What is range?
What is the range?
A set of numbers, or coordinates, written in the form (x,y).
What is ordered pairs?
Formed by the intersection of two number lines, the horizontal axis and the vertical axis.
What is a coordinate plane?

What is relation?
If any vertical line passes through the graph of a relation no more than once, then it is a function.
What is vertical line test?
A function graphed with a line or smooth curve.
What is continuous graph?

What is function notation?
The slope intercept form and the point slope form.
y = mx+b and (y2-y1)=m(x2-x1)
