Slope?

Slope (Rate of Change)

• A ratio that shows how one variable changes with respect to the other

• Can be written as a ratio (fraction) with the vertical change (rise) to the horizontal change (run)

• Remains constant between any two points

• Variable for slope : m

4 Types of Slope

What is a positive slope?

Poll

Which line has a slope of zero?

• Vertical

• Horizontal

Open Ended

Why is a vertical line undefined?

Let's find slopes of lines, given a graph.

Multiple Select

Check all statements that are true about slope.

• Slope is the change in x over the change in y.

• A negative line goes down from left to right.

• A zero slope is a vertical line.

• An undefined line does not have a horizontal change.

• A positive line increases from left to right.

Poll

Do I understand what slope means and how to find it given a graph?

• YES, I got this!

• NO, but I will STILL try the homework.
