Sports The baseball field below is on a coordinate grid with home plate at the origin. A batter hits a ground ball along the line shown. The player at (110, 70) runs along a path perpendicular to the path of the baseball. What is an equation of the line on which the player runs?
Step 1 Find the slope of the baseball's path.
Step 2 Find the slope of a line perpendicular to the baseball's path.
Which linear equation form should you use?
You know the slope. The player is located at a point on the line. Use point-slope form.
Step 3 Write an equation of the line on which the player runs. The slope is
Suppose a second player standing at (90, 40) misses the ball, turns around, and runs on a path parallel to the baseball's path. What is an equation of the line representing this player's path?
