what if there is no y intercept

If a line has no y-intercept, that means it never intersects the y-axis, so it must be parallel to the y-axis. … This slope of this line is zero. A real-life situation of a line that has no y-intercept is the equation of a vertical wall.

What do you write if there is no y-intercept?

Lines that have no y-intercept are vertical lines that are parallel to the y-axis, such as the line x=10. Lines that have no x-intercept are horizontal lines that are parallel to the x-axis, such as the line y=2.

Is it possible to have no y-intercept?

A line can have no x-intercept or no y-intercept, but not both. The x-intercept is where a line crosses the x-axis. … For example, a vertical line such as x=−4 has an x-intercept of (−4,0) , but there is no y-intercept because the line does not cross the y-axis.

How do you find the equation of a line with no y-intercept?

If the line does not have a whole number y-intercept, use the point-slope form of a line y-y1=m(x-x1) to find the equation of the line. Plug in the slope and one coordinate point from the line and solve for y.

Is 0 0 and y-intercept?

The y-intercept is (0, 0) As mentioned above, there is only one point that can be both an x- and y- intercept at the same time, the origin (0, 0).

What do you put If there is no y-intercept?

If a line never passes through the y axis, therefore having no y intercept, it must be parallel to the y axis, or a vertical line. It is also true that this line is perpendicular to the x axis.

Does every function have an y-intercept?

All linear functions cross the y-axis and therefore have y-intercepts. (Note: A vertical line parallel to the y-axis does not have a y-intercept, but it is not a function.)

What do you say when there is no y-intercept?

If a line has no y-intercept, that means it never intersects the y-axis, so it must be parallel to the y-axis. This means it is a vertical line, such as . This slope of this line is undefined. If the line has no x-intercept, then it never intersects the x-axis, so it must be parallel to the x-axis.

Can your y-intercept be 0?

The y-intercept is what y equals when x equals 0. The y-intercept can always be written as (0,y). If the y-intercept is 0, then that means the line passes …

What does a non zero y-intercept mean?

Its non-zero y-intercept gives information about the mass for zero volume which is not realistic. This is because, at zero volume, the mass should be zero. Therefore, the y-intercept must be zero.

Is it possible for there to be no y-intercept?

A line can have no x-intercept or no y-intercept, but not both. … A horizontal line crosses the y-axis, but not the x-axis, as long as y≠0 . For example, a horizontal line such as y=−3 has a y-intercept of (0,−3) , but there is no x-intercept because the line does not cross the x-axis.

How do you graph with no y-intercept?

If a line has no y-intercept (that is, it does not cross the y-axis) it must be vertical, parallel to the y-axis, with an equation like x=k1. Similarly, if it has no x-intercept, a line must be horizontal, with a slope of zero, parallel to the x-axis, with an equation like y=k2.

How do you graph If there is no y-intercept?

If a line has no y-intercept, that means it never intersects the y-axis, so it must be parallel to the y-axis. This means it is a vertical line, such as . This slope of this line is undefined. If the line has no x-intercept, then it never intersects the x-axis, so it must be parallel to the x-axis.

What does it mean when y is 0?

In math, a graph is a visual representation of how the variables in an equation relate to each other. … Your equation y = 0 is a linear equation since the variable has no exponent. Remember, the slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

What does an intercept of 0 mean?

Start with a regression equation with one predictor, X. … If X sometimes equals 0, the intercept is simply the expected mean value of Y at that value. If X never equals 0, then the intercept has no intrinsic meaning.

What value is zero for y-intercept?

An Introduction to Intercepts and Zeros The y-intercept is where the graph crosses the y-axis. The x-intercept is where the graph crosses the x-axis. What about the zeros of the linear function? The zero of the function is where the y-value is zero.

What does it mean when the y-intercept is 0?

If a line has no y-intercept, that means it never intersects the y-axis, so it must be parallel to the y-axis. This means it is a vertical line, such as . … This means it is a horizontal line, such as . This slope of this line is zero.
