A: ### Quick Answer

**In math, a ray is part of a line that has an endpoint at its starting point and extends in a certain direction into infinity.** Drawing a ray involves placing a line with one endpoint and an arrow point on the other end. To name a ray, the convention is to use the letter at the starting point followed by a letter near the arrow point.

One can use capital letters to name a ray, and over the two letters is drawn a ray symbol. An alternate convention used to name a ray is to use one lower case letter.

Two rays that diverge from a common starting point are called an angle. Another name for this starting point is the vertex of the angle.

## How do you find the y-intercept of a line?

A:To find the y-intercept of a line, substitute the values of x and y coordinates into an equation representing the line. Set x to 0, then solve for y. If the equation is already in the slope-intercept form of y = mx + b, the value of b is the y-intercept.

## What is a cubed number in math?

A:

Full Answer >**A cubed number in math is one that has been multiplied by itself three times.**They are called cubed numbers because the height, width and depth of a cube are all the same. The cubes of whole numbers, or counting numbers, including zero, are called perfect cubes.Filed Under:
