A 4 quadrant coordinate graph with a line going through the points (negative 1, comma 3) and (1, negative comma 1). Review what you know about graphs by answering the following questions.   

  1. What is the equation of the line graphed at right?

    Use the -intercept and the slope to write an equation of the line in the form of . (Create a slope triangle if you need one).

  2. What are its - and -intercepts?

  • Remember that the -intercept is the point on the graph where and that the -intercept is the point where .
