IM 8.2.11 Practice: Writing Equations for Lines
For each pair of points, find the slope of the line that passes through both points. If you get stuck, try plotting the points using this applet and drawing the line through them.

Is the point on line?
Explain how you know.
Write a rule that would allow you to test whether is on line .
Consider the graphed line.
Mai uses Triangle A and says the slope of this line is . Elena uses Triangle B and says no, the slope of this line is 1.5. Do you agree with either of them?
Explain.
A rectangle has length 6 and height 4.
Which of these would tell you that quadrilateral is definitely not similar to this rectangle? Select all that apply.
