Find the y-intercept x=-4

Problem

x=−4

Solution

1. Identify the definition of a y-intercept. The y-intercept of a graph is the point where the graph crosses the y-axis, which occurs when x=0

2. Analyze the given equation. The equation x=−4 represents a vertical line where every point on the line has an x-coordinate of −4

3. Substitute x=0 into the equation. Setting x=0 in the equation 0 = -4$ results in a contradiction.

4. Conclude that because the x-coordinate is constant at −4 the line is parallel to the y-axis and never crosses it.

Final Answer

y-intercept: None
