- For the second graph (Equation 7), identify two points on the line. Let's use the points (-4, 3) and (4, -3).
- Calculate the slope (m) using the formula m=x2−x1y2−y1.
- Using the points (-4, 3) and (4, -3):
m=4−(−4)−3−3=8−6=−43
- The y-intercept (b) is the point where the line crosses the y-axis. From the graph, it is clear that the line crosses the y-axis at (0, 0).
