Lesson 10: Practice Problems

Problem 1

For each graph, calculate the slope of the line.

  1. graph of a line through points 2 comma 6 and 8 comma 4.
  2. graph of a line through points -5 comma 7 and 1 comma 1.
  3. graph of a line through points -6 comma -3 and -2 comma -8.

Problem 2

Match each pair of points to the slope of the line that joins them.

  1. and

  2. and

  4. and

  5. and

  1. 4

Problem 3

Draw a line with the given slope through the given point. What other point lies on that line?

A x y axis with points A-F plotted. The coordinates are: A (2,7) B (5,-2) C (-4,3) D (10, 5) E (2,0) F (4,-3)

  1. Point A, slope =

  2. Point A, slope =

  3. Point C, slope =

  4. Point E, slope =

Problem 4 From Unit 3 Lesson 8

Make a sketch of a linear relationship with a slope of 4 and a negative -intercept. Show how you know the slope is 4 and write an equation for the line.
