How to find the y-intercept without graph?

Understand the Problem

The question is asking for a method to determine the y-intercept of a function or equation without using a graph. The y-intercept is found by evaluating the equation when x is zero.

Answer

Set x = 0 and solve for y.

To find the y-intercept of an equation without graphing, set x = 0 and solve for y. The y-intercept will be at the point (0, y).

Answer for screen readers

To find the y-intercept of an equation without graphing, set x = 0 and solve for y. The y-intercept will be at the point (0, y).

More Information

The y-intercept is where the line crosses the y-axis, and this occurs when the x-value is 0.
