slope-intercept form

Work Step by Step

$y = mx + b$ is the slope-intercept form of a linear equation. In this equation, $m$ is the slope, and $b$ is the y-intercept. $y - y_1 = m(x - x_1)$ is the point-slope form of a linear equation. In this equation, $m$ again is the slope whereas $(x_1, y_1)$ is a point on the graph.
