What would a non-zero y-intercept signify?

If B is non-zero, then the y-intercept, that is the y-coordinate of the point where the graph crosses the y-axis (where x is zero), is CB , and the slope of the line is −AB .

What does it mean when y-intercept is zero?

The y intercept of a graph is the point where the graph intersects the y-axis. We know that the x-coordinate of any point on the y-axis is 0. So the x-coordinate of a y-intercept is 0.

What does a nonzero F intercept tell you?

What does a non-zero intercept tell us in the case where it defies reason? It tells is that we need to rethink what we are trying to model; that we have misinterpreted something along the way and we need to go back and rectify it.

Is the y-intercept always 0?

The Y intercept of a straight line is simply where the line crosses the Y axis. In the above diagram the line crosses the Y axis at 1. The Y intercept is equal to 1 and the point is written as (0,1). Notice that for the y-intercept the x-coordinate of the point is always zero..

Why the y-intercept of the expense function is never 0?

The y-intercept for a variable cost is always zero because if there is no activity, there is no cost.

What is the y-intercept of an undefined line?

Examples of Undefined Slope Example 1: Find the equation of the line that passes through (1,2), with an undefined slope. Solution: Any line that has an undefined slope is a vertical line, that has no y-intercept. Therefore the equation of a line with an undefined slope is x = a, where a = x-intercept.

What is an undefined slope?

What Is an Undefined Slope? The slope of a line is undefined if the line is vertical. If you think of slope as rise over run, then the line rises an infinite amount, or goes straight up, but does not run at all.

Is the y-intercept always at 0 1?

To find the y-intercept, we look for the point where the line crosses the y-axis. The line crosses the y-axis where the y-value is 1. The x-value is always 0 for every point on the y-axis so the y-intercept is (0, 1).

What is Y 0 called?

The x-intercept occurs when y is zero. The y-intercept is the point, (0, b), where the graph crosses the y-axis.

Can y-intercept be negative?

A positive y-intercept means the line crosses the y-axis above the origin, while a negative y-intercept means that the line crosses below the origin.

What does it mean when slope is undefined?

The undefined slope is the slope of a vertical line. The x-coordinates do not change, no matter what y coordinates are. The vertical lines rise straight up or fall straight down, whereas they don’t run left or right.
