Geometry question... MEDAL will be awarded! 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? Where is the bug when t = 2? when t = −1? when t = 1.5? What does a negative t-value mean?

OpenStudy (calculusxy):

No. I will do it right now.
