Find the y-intercept y=-2

Problem

y=−2

Solution

1. Identify the form of the equation. The given equation y=−2 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=−2 does not contain an x variable, the value of y remains −2 regardless of the value of x

4. Determine the coordinate. When x=0 y=−2 which gives the point (0,−2)

Final Answer

y=−2⇒y-intercept=−2
