!!!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
