PLEASE HELP! HURRY! since its 2 questions, ILL GIVE MORE POINTS!
VARVARA [1.3K]

A. m = 0 || This is incorrect, because m being equal to 0 is a solution in and of itself.

B. m = m || This is incorrect, because m being equal to itself means that there are an infinite number of solutions.

C. 2m + 1 = m - 2 | m = -3 || This is incorrect, because m can be solved for and has a solution.

D. m + 4 = m - 4 | 4 = -4 || This is correct because 4 is not equal to -4, and thus there is no solution.

Hope this helps!! :)

Remember slope is \dfrac{rise}{run}. In the graph we can just pick two points on the line to find the rise and run between. Let's say we choose (0,3) and (1,7). Between those points there is 7-3=4 rise and 1-0=1 run. So the slope is \dfrac{4}{1}=\boxed{4}

Using unit circle you can count up until you get the answer of 60º. Alternatively you can multiply 2pi/6 by 180/pi which will give you the same answer.
