Amotorcycle is driving due north at 50 mph relative to the ground a blue truck is driving the same direction as a motorcycle at 56 mph with the respect to the ground. a red sports car is driving due south at 75 mph relative to the ground. a bird is flying due south above the red car. the bird's speed is 140 mph with respect to the motorcycle.

because it says use -2,0,and 2 for x, we can plug those numbers into the equation. y/4=3/4(-2)+2   y/4= -1 1/2 +2 now to get x by itself, we can multiply each side by 4. y=-6+8 which equals y=2 when x=-2. now you can do the same thing with 0 and 2 as x. you get y=8 when x=0 and y=14 when x=2.

x   |   y

-2 |   2

0   |   8

2   |   14

probably not the "magnets"in the magnet, so to speak, are thought to be electrons orbiting in shells. vurrent loops two sides to the loop
