The y-intercept is the point at which a linear equation crosses the y-axis on the x=0 plot point. The equation to determine both the slope and the y-intercept of a line is y=mx+b.

To plot a linear equation, remember that the slope-intercept form is y = mx + b, where "m" is the slope, or steepness, of the line and "b" is the y-intercept, where it crosses the y-axis, or the ...
