Y = 0
The y-axis has the equation x=0, so every point on the y-axis has an x coordinate of zero.
The equation y = mx + b is the equation for a line in slope intercept form, with m being the slope, and b being the y-axis intercept.
Typically the y-axis is the vertical axis and x-axis if horizontal. This is by convention and not required.This is used to plot a binomial (two variable) equation.
y = 3x + 1 is a linear equation - it is the equation for a graph of a straight line that crosses the y axis at 1 and the x axis at -1/3, and has a gradient (slope) of 3.
