WebThe function intercepts points are the points at which the function crosses the x-axis or the y-axis. These points are called x-intercepts and y-intercepts, respectively. What is the formula for slope and y-intercept? The slope-intercept form of a linear equation is y = mx + b, where m is the slope of the line and b is the y-intercept.
