Finding Line Intersections in Excel

Discover the intersection of two straight lines in Excel efficiently. Utilize the built-in SLOPE and INTERCEPT functions to calculate the precise point where two lines cross.

Step-by-Step Intersection Calculation

Begin by determining the linear equations of both lines, which adhere to the y=mx+c format. Ensure each line's equation is established to find their intersection.

Set the equations equal to each other to isolate the x-coordinate. This equates to solving the system t=m1s+c1 and t=m2s+c2, where 's' is the x-coordinate and 't' is the y-coordinate of the intersection.

Solve for 's' using the formula s=(c2-c1)/(m1-m2). Apply the SLOPE and INTERCEPT functions in Excel to find the values of 'm' (slope) and 'c' (y-intercept) for each line.

Once 's' is found, calculate 't' by substituting 's' into either line's equation, t=m1*s+c1. This gives you the y-coordinate of the intersection point.

Visualizing the Intersection

Use Excel's scatter plot with straight lines feature to visualize the point of intersection for a clearer understanding and confirmation of the calculated intersection.
