slope

Y=mx+b

Run

the run of a line is the change in the horizontal position, or the difference between the x-coordinates of two points on the line.

Defending line

Negative trend

Inclining line

Positive trend

Slope=0

Horizontal line

Slope=undefined

Vertical line

Initial condition

Where the line crosses the y axis

Rate of change

A value that results from dividing the change in a function (y-values) of a variable by the change in the variable (x-values). It is another name for slope.
