Find the y-intercept y=-3

Problem

y=−3

Solution

1. Identify the form of the equation. The given equation y=−3 represents a horizontal line where the ycoordinate is constant for every value of x

2. Recall the definition of a yintercept. The yintercept is the point where the graph crosses the yaxis, which occurs when x=0

3. Substitute x=0 into the equation. Since the equation y=−3 does not depend on x the value of y remains −3

4. Determine the coordinates. The yintercept is the point (0,−3) or simply the value y=−3

Final Answer

y=−3
