Step 3: Find the Intersection Point with $ x = 3 $ In linear equations and coordinate geometry, determining the intersection point of two lines is a fundamental task. Step 3 in this process focuses on evaluating what the line equation becomes when $ x = 3 $. This troubleshooting step helps identify a specific point on a graph, often used in math problems, data analysis, and applied sciences. ### What Does It Mean to Find the Intersection at $ x = 3 $? The equation $ x = 3 $ represents a vertical line that passes through all points where the $ x $-coordinate is 3, regardless of the $ y $-value. To find the intersection point at this value of $ x $, we substitute $ x = 3 $ into the equation of interest—usually another linear equation such as $ y = mx + b $. This substitution allows you to compute the corresponding $ y $-coordinate, revealing the exact point of intersection.
