Let the speed off the walk way be x and speed of the walkway be y
x+y=6....i
x-y=2....ii

2x=8
thus
x=4 ft/s
and
y=6-4=2 ft/s

Inessa05 [86]

Answer:

Step-by-step explanation:

The slope of all lines in quadrant 1 is positive. FALSE

The slope of a line does not depend on the quadrant.

The slope of <u>all lines</u> that pass through the origin is undefined.FALSE

The slope of some lines that pass trough the origin are undefined ( lines that are vertical have undefined slope)

The larger the slope, the longer the line.FALSE

The lines do not get longer or shorter because they go to infinity in both directions.

The larger the magnitude of the slope value, the steeper the line. TRUE

The larger the absolute value of the slope the steeper the slope.
