Find the x-intercept
\Look for the point where the line crosses the x axis.
\The line crosses at (6,0).
\The x-intercept is 6 because it is the x coordinate of the point where the line
\crosses the x axis.
\The x-intercept is 6.
Find the y-intercept.
\Look for the point where the line crosses the y axis.
\The line crosses at (0,20).
\The y-intercept is 20 because it is the y coordinate of the point where the line
\crosses the y axis.
\The y-intercept is 20.
At the time zero seconds the eagle at height 20 feet from ground.
\After 6 seconds eagle reaches the ground.
