X intercept: -5 Y intercept: +3
by shoving it up your booty
-- If you know the general shape of a graph, and you can quickly determine the x- and y-intercepts, that's often enough information to make a pretty accurate sketch of the graph. -- In particular, if the equation is a linear one, then you know the graph will be a straight line; and then, as soon as you know the x- and y-intercepts, just draw the line between them and you don't need anything else ... that's your graph.
The y-intercept is the value of the function when 'x' is zero. That is, it's the point at which the graph of the function intercepts (crosses) the y-axis. The x-intercept is the value of 'x' that makes the value of the function zero. That is, it's the point at which 'y' is zero, and the graph of the function intercepts the x-axis.
Y=mx+b. this equation is used for straight lines on a graph. Each letter represents something different. Y is the y-axis (the vertical lines of the graph). M is the slope. X is the x-axis (the horizontal lines of the graph). B is the y-intercepts (where the line intercepts with the y axis).
