Graph this line using the slope and y-intercept:
y = 2x + 8
Click to select points on the graph.

Answer

The equation of the line is in the slope-intercept form y = mx + b, where m is the slope and b is the y-intercept.

  1. The slope (m) is 2, which means the line rises 2 units for every 1 unit it runs to the right.
  2. The y-intercept (b) is 8, which means the line crosses the y-axis at (0, 8).
  3. To graph the line, start at the y-intercept (0, 8).
  4. From (0, 8), use the slope to find another point: move 1 unit to the right and 2 units up to reach (1, 10).
  5. Plot these points and draw a line through them to complete the graph.
