Finding the Slope of a Line Given a Graph or Two Points

In the equation y=mx+b, what does the m represent?

• slope

• y-intercept

• linear

• point-slope

Which company shows a greater rate of change?

• Water's Edge Rafts

• Ryan's Rafts

Which graph matches the table?

• A

• B

• C

• D

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

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

When finding slope from a graph...

• use change in y over change in x

• locate two points and create a right triangle, then rise over run

• x coordinate divided by the y coordinate

• pick only two negative points on the graph and subtract

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

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

• m = -3

• m = 1/3

• m = 3

• m = -1/3

The rate of change between any two points on a line. The ratio of the rise, or vertical change, to the run or horizontal change.

• b

• horizontal change

• vertical change

• slope
