Weband a second solution of the equation is (4, 0). We can now use the ordered pairs (0, 3) and (4, 0) to graph Equation (1). The graph is shown in Figure 7.6. Notice that the line crosses the x-axis at 4 and the y-axis at 3. For this reason, the number 4 is called the x-intercept of the graph, and the number 3 is called the y-intercept. WebAug 18, 2024 · Step 1: Identify two points on the line. Any two points will do, but it is recommended to find points with nice x and y coordinates. Step 2: The slope is the rise over the run. Thus if the points have coordinates ( x 1, y 1) and ( x 2, y 2), then the slope is: S l o p e = R i s e R u n = y 2 − y 1 x 2 − x 1 Example 6.2. 1
