Consider the equation −3x + y = − 2
A line parallel to the above line would have a slope of

A line perpendicular to the above line would have a slope of

Note: Your answers have to be reduced fractions.

3 parallel-1/3 perpendicular

Step-by-step explanation:

The equation can be rearranged to ...

  y = 3x -2

The slope is the x-coefficient, 3.

A parallel line will have the same slope: 3.

A perpendicular line will have the opposite inverse slope: -1/3.

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm
