Use the graph to answer the question, (0, 0), (1, 3), (2, 6), (3, 9).
Use similar triangles to determine the slope of the line.
The slope is _________
3
To determine the slope of the line, we can choose any two points on the line and use the formula:
slope = (y2 - y1) / (x2 - x1)
Let's use the points (0, 0) and (1, 3):
slope = (3 - 0) / (1 - 0)
slope = 3 / 1
slope = 3
Therefore, the slope of the line is 3.
