Finding Slope Equation from Two Points or a Table

What is the slope represented in the table?

Find the slope of:
(1,8) and (3,12)

• 2

• 1/2

• 9/7

• -2

Find the slope of:
(7,1) and (-2,1)

• 0

• -1/2

• undefined

• -8

What is the slope?

• -1/3

• -3

• -4

• 5

Find the slope from the table:

When finding slope from a table....

• Use y = mx+b

• Use y1-y2, x1-x2

• Use m = change in x / change in y

• Use m = change in y / change in x

When finding slope from a set of points...

• Use (m = y2 -y1 / x2 - x1)

• Use change in y / change in x

• Use (m= y1-y2 / x1-x2)

• Use y = mx+b

Rate of change is finding the...

• f(x)

• y-intercept

• slope

• x coordinate

Given points (5,2) and (4,-1), what is the slope?

• m = -3

• m = 1/3

• m = 3

• m = -1/3

What is slope?

• two points

• run over rise

• Division of vertical change by horizontal change between two points

• Change in x over change in y
