Yes, x = -3 would represent a vertical line at abscissa -3, parallel to the y-axis.
A cartesian graph is a graph in which y is some function of x. This is the 'normal' type in which you can give an x and y coordinate. Other types include polar in which modulus is a function of argument, but there are loads of varieties and forms.
b is the variable for the y-intercept, or how far up or down the graph is shifted.
A graph about masses and volumes would represent density.
Tables and graph represent relations by showing the distribution of occurrence.
A point can represent a piece of data or an (x,y) value.

X-Axis is manipulated variable. Y-Axis is responding variable
The Y-axis

Assuming the graph is: x = - 305 y, then the y intercept is at y = 0Assuming the graph is: x - 3 = 5y, then the y intercept is at y = -3/5The main point for you to realize here is that a graph represents an equation,and " -305y " is not an equation. So some kind of assumption has to be madein order to come up with something that can be graphed.

A graph is typically represented in terms of a y-axis (vertical), x-axis (horizontal) and sometimes a z-axis as well (at right angles to the y & x) if it's a 3-D graph.

The waveform of the electrical signal in terms of amplitude on y and period in x.
The velocity at the starting point (when t = 0).
