Unit 2: Identifying the Intersection of Lines

Answer both of the questions below. Please do all your work on a piece of scrap paper, and, when you are done, check your answers against the ones provided.

  1. Using the graph below, answer the following questions.

  1. At what coordinates does the line AC intersect the y-axis?
  2. At a y value of 200, what is the x value for line AC?
  3. What are the coordinates of the intersection of lines AC and RS?

  1. The graph below has two intersecting lines, R and S.

    Line S shifts to the left (shifts from S1 to S2). This shift is illustrated on the graph below. How is the point of intersection affected by this shift (how do the coordinates of the intersection change)?
