The given line is in point-slope form.
All options are also in point-slope form.
We can read the slope off the point-slope form easily.
The slope is 2.
A perpendicular to that line must have slope -1/2.
Only one line in the options has slope -1/2 and it's option B.
I KNOW THA WEY but wut are you saying the mean price
Answer:
-60+30=(-30)
Step-by-step explanation: The whale was swimming 60 feet BELOW sea level. That's negative. Then it swims up 30 feet, that's positive. Add to get -30, since -60 is the greater number although not in value. you get -30, so move the dot up , and the whale is now 30 feet below the surface.
