Slope and Linear Pairs

Definitions

• Slope: how steep a straight line is
• Linear Pair-a pair of adjacent angles whose noncommon sides are opposite

Slope

• Equation: Y=MX+B
• M= the slope of the line B=is the y-intercept
• ex. y=2x+6
• 2 is the slope of the line and B is the y-intercept
• Slope can be found using rise over run

Standard to Slope

• 2x+y= -2 this is standard form
• To change into slope intercept form subtract 2x 
• Resulting in y=-2x-2
• The first -2 being the slope of the line 
• The second -2 is the y-intercept

Rise Over Run

• Rise over run is:
• The change of y over the change of x
• An example of this is the background of this slide
• Also, slope can be classified as either positive, negative, zero, or 
• undefined

Linear Pair

• Linear pair is a pair of  adjacent angles
• Adjacent angles are angles that are next to each other
• ex. supplementary angles
• So, linear pairs are created by two lines intersecting
• The background of this slide is an ex. of linear pairs
