  1. What is the slope of the line?

    In the equation of a line, slope.

  2. What is the y-intercept of the line?

    In the equation of the line, -intercept.

    (0, −4)

  3. Graph the line.

  • Plot the -intercept and then use the slope (the top value is and the bottom one is ) to find another point, and draw a line connecting the points. You should be able to draw a slope triangle on your graph that matches the slope you found in part (a).

Use the eTool below to graph the line and determine the slope and -intercept.
