Answer:
m = - 1/6
Step-by-step explanation:
Since 2/3 is larger than 1/2, m is going to be less than 0 because you have to subtract 2/3 to get to the right. That makes a and b incorrect. I can tell you that the answer doesn't appear to be there.
m + 2/3 = 1/2 Subtract 2/3
m = 1/2 - 2/3 The common denominator is 6
m = 3/6 - 4/6 Do the subtraction
m = - 1/6
