Find the y-intercept x=-3

Problem

x=−3

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=−3 represents a vertical line that passes through all points where the x-coordinate is −3

3. Substitute the condition for a y-intercept (x=0 into the equation. Setting x=0 in the equation 0 = -3$ results in a contradiction.

4. Conclude that because the x-coordinate is constant at −3 it can never be 0 Therefore, the line is parallel to the y-axis and does not intersect it.

Final Answer

y-intercept of *x=−3=None
