The key concept here is that the line must pass BETWEEN points (1, 3) and (2, 3)
So, if we find the slope from (–1, 1) to (1, 3) and the slope from (–1, 1) to (2, 3), then the slope of the line must be BETWEEN the two slopes we calculated.
Slope from (–1, 1) to (1, 3) = \(\frac{3 - 1}{1 - (-1)}=\frac{2}{2}=1\)
Slope from (–1, 1) to (2, 3) = \(\frac{3 - 1}{2 - (-1)}=\frac{2}{3}=0.6666666...\)
So, the correct answers will have values that are BETWEEN 0.6666666... and 1.
(A) 1/2 = 0.5
0.5 is not BETWEEN 0.6666666... and 1.
Eliminate A
(B) 3/5 = 0.6
0.6 is not BETWEEN 0.6666666... and 1.
Eliminate B
(C) 3/4 = 0.75
0.75 IS BETWEEN 0.6666666... and 1.
Keep C
Answer: C
