9 Extended: Working with the Slope

Complete the questions below before our next class.

  1. A line contains the point A(1, 3) and has a slope of 3. Find the coordinates of two other points on the same line.
  2. A line contains the point A(0, 5) and has a slope of \(\displaystyle{-\frac{2}{3}}\). Find the coordinates of two other points on the same line. (Hint: associate the negative sign with the number in numerator before trying to find other points on the line.)
  3. Consider the point A(1, 1). On a grid, graph a line with a slope of \(\displaystyle{\frac{3}{5}}\) that passes through point A, and a line with a slope of \(\displaystyle{-\frac{5}{3}}\) that also passes through point A. What do you notice about the two lines?

Our test on real numbers, sets, and radicals (corresponding to material in Chapters 2 and 4 of our textbook) will be on Monday, October 22.

As part of your preparation for the test, I suggest you look at the following review questions from the textbook.

Review Set 2A questions 1–11
(and/or Review Set 2B questions 1–10 if you want extra practice)
