Finding Slope Ratio Method

slope

• how steep a line is, rise over run,

• the type of line on a graph

Find the slope of:

(7,1) and (-2,1)

• 0

• -1/2

• undefined

• -8

Find slope of:

(-2,3) and (4,-5)

• 4/3

• -4/3

• 3/4

• -3/4

Find the slope

• -2/3

• 3/2

• -3/2

• 2/3

Why do we want to think of slope as a fraction?

• rise/run or change in y over change in x

• run/rise or change in x over change in y

• Fractions make things better

• Because running makes the problem go faster!

Given the graph above, use the slope formula to determine slope.

• -5/4

• -4/5

• 4/5

• 5/4

Slope is written as a(n) ________.

• Ordered Pair (x, y)

• Fraction

What number should be put in the denominator for the X value?

• 4

• 2

Given the graph above, use the slope formula to determine slope.

• 2

• 1/2

• -1/2

• -2

Find the rate of change

• 3

• -3

• -1/3

• 1/3
