1. A bug is moving along the line 3x + 4y = 12 with constant speed 5 units per second.

The bug crosses the x-axis when t=0 seconds. It crosses the y-axis later. When? t=1

Where is the bug when t=2? (-4 , 6) when t= -1? ( 8, -3)

when t = 1.5 ? (-2 ,18/4)

What does a negative t value mean?(Headbang)

Are my answers correct?

I could not answer the last problem.

2. Find the parametric equations to describe the line

3x + 4y = 12. ( t , -3/4t +3 ) Use your equations to find the coordinates for the point that is three-fifths of the way from (4,0) to (0,3). (8/5 , 9/5)

By calculating some distances verify that you have the correct point.
