Question

What is a y intercept

Answer 1

In the equation of a straight line (when the equation is written as "y = mx + b"), the slope is the number "m" that is multiplied on the x, and "b" is the y-intercept (that is, the point where the line crosses the vertical y-axis). This useful form of the line equation is sensibly named the "slope-intercept form".

Answer 2

A y-intercept is the point at which a function hits the y-axis on a graph.

Explanation:

It's called this because it's where the function intersects the y-axis.
