Understanding Slope-Intercept Form
The slope-intercept form of a linear equation is given by y = mx + b, where:
- m is the slope of the line, representing the rate of change of y with respect to x.
- b is the y-intercept, the point where the line crosses the y-axis (i.e., the value of y when x = 0).
This calculator helps you find the equation of a line in this form when you know the slope (m) and a point ((x1, y1)) that the line passes through. By substituting these values into the point-slope form and rearranging, we derive the slope-intercept form. Use this tool to easily visualize and understand linear equations.
