IM 8.2.10 Lesson: Meet Slope

[size=150]Write some numbers that are equal to [math]15\div12.[/math][/size]
The figure shows three right triangles, each with its longest side on the same line. Your teacher will assign you two triangles.
Explain why the two triangles are similar.
Complete the table.
Draw two lines with slope 3. What do you notice about the two lines?
Draw two lines with slope 1/2 . What do you notice about the two lines?
As we learn more about lines, we will occasionally have to consider perfectly vertical lines as a special case and treat them differently. Think about applying what you have learned in the last couple of activities to the case of vertical lines. What is the same?
What is different?
Here are several lines. Match each line shown with a slope.
One of the given slopes does not have a line to match. Draw a line with this slope on the empty grid below.
