Slope+(Standard+5-6)



Remember: 1. " Same signs add and keep. Different signs subtract. Keep the sign of the larger number...and you will be exact! " 2. Subtracting a negative changes to addition. ex. 2 - - 3 = 2 + 3 = 5

Definition of Slope: Slope is used to describe the steepness, incline, gradient, or grade of a straight line.

Slope Formula = m = (rise)/(run) = (y2-y1)/(x2-x1)

Rate of Change is the difference between two output values divided by the difference between the corresponding input values.
 * SAME AS SLOPE**

Quadrant II: (negative x coordinate,positive y coordinate) Quadrant III: (negative x coordinate ,negative y coordinate ) Quadrant IV: ( positive x coordinate, negative y coordinate)
 * Quadrant I: (positive x coordinate, positive y coordinate)

If a line goes up from left to right it's slope is...positive

If a line goes down from left to right it's slope is... negative

If a line is horizontal (flat) it's slope is... zero

If a line is vertical (up & down) it's slope is... undefined

--Steeper lines have a greater slope than that of flatter lines.**


 * THOU SHALLT NOT DIVIDE BY __ZERO!__

- Dividing by zero is always...undefined.S

The slopes of two parallel lines are **__same slope.__**

The slopes of two perpendicular lines are **__negative reciprocals__** (opposites).
