You would square 3968 and subtract 1.
Both graphs x =4 and y =4 will be perpendicular to each other.
- The graph of x = 4 is a vertical line down the Graph scope
- The graph of y =4 is a horizontal line side the Graph scope.
Both the Lines will meet exactly at ( 4, 4 ) perpendicularly at each other both of them intersecting at 90 degrees.
Vertical and Horizontal lines are perpendicular to each other (90 Degrees).
