What is liner function?
an equation that makes a straight line when it is graphed
What is a liner equation?
a transformation made by turning or spinning a figure around a given point
What is rotation?
all values of x and y in all directions forever
What is the coordinate plane?
a number that can NOT be expressed as a ratio of two integers or as a repeating or terminating decimal, like Pi or any square root of an imperfect square
What is the definition of a irrational number?
a measure of the steepness of a line on a graph - m - rise over run - pattern of the y-outputs

What is a function?
points where a line crosses the x-axis and y-axis
What is the definition of intercept?
opposite the right angle - it is also the longest side of a right triangle
What is the definition of hypotenuse?
one of three equal factors (multiplication) of a number - it is the side of a cube
