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.

slope formula
Finding slope
look for a starting point on the y-axis then find two points
Slope of an equation
look for the fraction with the x then find your y intercept

substitute y with 0 and sovle the equation
Findin the X-intercept
Substitute 0 for x in the equation
