Two motorcycles start at the same point. one motorcycle travels 15km due north and stops.
the second motorcycle travels 32 km due west and stops. which value is closest to the distance between the motorcycles when they stop?

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.

you,

the answer is 21%.

parallel lines have the same slope. so if the green line has a slope of -4, the slope of the red line is also -4.
