Answer:

3/2

Step-by-step explanation:

When you rearrange the equation into y=mx+b, you get y=-2/3x-15

The slope of the given line is -2/3 and you have to take the opposite reciprocal so flip the fraction and change the sign.

This gives the slope 3/2

How do I convert radians to degrees? Is it pi/180 or 180/pi? I get them confused! Thanks
o-na [289]
It could be either one, depending on whether you intend to multiply or divide.

When you convert, just remember that degrees ==> less radians,
and radians ==> more degrees.  Then you can always check the
results, and make sure that you used the right conversion factor
in the right direction.
