If cosΦ is lesser than zero (negative) it must be in quadrant 2 or 3 because cos is always positive in quadrants 1,4.
Turn it into a improper fraction and then multiply both the numerator and denominator together!
So like 1 1/2 x 2 1/2
Turn that into improper fractions and get 3/2x5/2
then you get 15/2 which is 7 1/2
To get the answer, you must solve 5656 / 3434 which = 1.64
The closest answer choice that matches this is the last one: 1 3/5 cup
The answer for finding the slope is -1/2
