Slope-Intercept Form of a Line
y = mx + b This is the slope-intercept form of a linear equation where m = the slope of the line b = the y-intercept (0, b) Example y = 2x + 3

Slope-Intercept Form of a Line
y = mx + b This is the slope-intercept form of a linear equation where m = the slope of the line b = the y-intercept (0, b) Example y = 3x – 4 The slope is 3. The y-intercept is –4 i.e. (0, -4).
