Example: Writing Linear Equation
The graph of a linear function is shown. Use two points on the line and the formula to find its slope. Write the equation for this line using the point-slope form, . Then, rewrite the result in slope-intercept form, . Use the slope-intercept form to determine the -intercept, .
- Determine the slope of the line.
- Use the point-slope form to write the equation for this line.
- Rewrite the equation in slope-intercept form.
- Determine the -intercept of the line.
