Plot the points A (2, 4) and B (4, 2) on a graph sheet and draw a line passing through these two points.
Question:
Plot the points A (2, 4) and B (4, 2) on a graph sheet and draw a line passing through these two points. Extend the line on both sides to meet the coordinate axes. What are the coordinates of the points where this line meets the x-axis and the y-axis?
Solution:
From the graph, we can see that after extending line AB, it cuts x-axis at P(6,0) and y-axis at Q(0,6).
