11.1 Slope, Distance & Midpoint Homework
1. Using the slope formula only, find the slope of the line segment that has the following endpoints. Write
your slope in simplest form.
a. 𝐴𝐴(−2, 4) and 𝐡𝐡(8, 10)
b. 𝐢𝐢(−10, 3) and 𝐷𝐷(11, −9)
c. 𝐸𝐸(2, 11) and 𝐹𝐹(−2, 3)
2a. On the diagram below, draw a line that passes through point C and is parallel to οΏ½οΏ½οΏ½οΏ½
𝐴𝐴𝐴𝐴 . Explain how you
created your line.
b. If the line you drew in #2(a) was extended, would it eventually pass
through the point 𝐸𝐸(18, −8)? Explain how you determined your
yes/no answer.
οΏ½οΏ½οΏ½οΏ½ parallel, perpendicular or
3. Given the four points 𝐴𝐴(−3, 5), 𝐡𝐡(1, 13), 𝐢𝐢(4, 2) and 𝐷𝐷(10, 5) are οΏ½οΏ½οΏ½οΏ½
𝐴𝐴𝐴𝐴 and 𝐢𝐢𝐢𝐢
neither? Justify your answer.
4. If each of the following represents the slope of a line, give the slope of a line that is perpendicular to it.

1
d. π‘šπ‘š = − 3
e. π‘šπ‘š = 1
5. If a line was drawn through point 𝐢𝐢 in the diagram such that it is
οΏ½οΏ½οΏ½οΏ½ , at what coordinate point would the two lines
perpendicular to 𝐴𝐴𝐴𝐴
intersect?
6. Find the distance between each set of points using the distance
formula.

a. (−5, 7) and (9, 15)
b. (−8, 12) and (5, 4)
8. For the points below, find three quantities: the slope between the points, the midpoint between the
points and the distance between the points. Show all calculations. Simplify all answers.
