5.2.2 Point-Slope Form (continued) Example 4 Using Two Points to Find Intercepts In Example 4, Prof. Burger uses two points on a line to find the intercepts of that line.
Recall that the equation of a line can be used to find the line’s intercepts. To find the x -intercept of a line, substitute 0 for y and solve for x . To find the y -intercept of a line, substitute 0 for x and solve for y .
Example 5 Problem Solving Application
Prof. Burger writes the equation of a line using two ordered pairs from a given table in Example 5. Note that in Step 1, any two points from the table can be used to find the slope. Additionally, in Step 2, any point from the table can be used to write the equation of the line in point-slope form.
