Slope-Intercept

Type in the following equation. Click on the line and turn it purple. Now answer the following: Does the graph slope up or down? What ordered pair does the line cross the y-axis?

Type in the following equation. Click on the line and turn it blue. Now answer the following: Does the graph slope up or down? What ordered pair does the line cross the y-axis?

Type in the following equation. Click on the line and turn it green. Now answer the following: Does the graph slope up or down? What ordered pair does the line cross the y-axis?

Type in the following equation. Click on the line and turn it red. Now answer the following: Does the graph slope up or down? What ordered pair does the line cross the y-axis?

Type in the following equation. Click on the line and turn it pink. Now answer the following: Does the graph slope up or down? What ordered pair does the line cross the y-axis?

Type in the following equation. Click on the line and turn it orange. Now answer the following: Does the graph slope up or down? What ordered pair does the line cross the y-axis?

Type in the following equation. Click on the line and turn it grey. Now answer the following: Does the graph slope up or down? What ordered pair does the line cross the y-axis?

For the graphs that slope up, look at the number in front of the x in the equation. Is it positive or negative?

For the graphs that slope down, look at the number in front of the x in the equation. Is it positive or negative?

Now look at where the graphs cross the y-axis. Compare this to the number at the end of each equation. Record your observations.
