!!!SLOPE!!!
Slope is a measure ofSteepness.
Types of SlopePo
sitive
NegativeZero
Undefinedor
No Slope
Slope is sometimesreferred to as the“rate of change”
between 2 points.
If given 2 points on a line, you may findthe slope using theformula m = y2 – y1
x2 – x1
Find the slope of the line through the
points (3,7) and (5, 19).x1 y1 x2 y2
m = 19 – 7 5 – 3
m = 12 2 m = 6
(3, 4) and (-6, -2)m = -2 – 4 -6 – 3
m = -6 -9
m = ⅔
If given an equationof a line, there are2 ways to find the
slope and y-intercept.
One method is towrite the equation inslope-intercept form,which is y = mx + b.
slopey-intercept
Find the slope andy-intercept of the
following equations. y = 3x + ½
slope= 3 y-intercept = ½
3x + 5y = 10 First, solve the equation for y.
3x + 5y = 105y = -3x + 10y = -3/5 x + 2
m= -3/5 b = 2
If given the graphof a line, find the
slope by using the“triangle” method to
find the rise over run.
rise = 4
run = 5
m= rise runm= 4/5
