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).
