Answer:
1/3
Explanation:
Compute the slope of the line through the following points:
p_1 = (-4, 1) and p_2 = (2, 3)
The slope of the line through (x_1, y_1) and (x_2, y_2) is:
(y_2 - y_1)/(x_2 - x_1)
Substitute (x_1, y_1) = (-4, 1) and (x_2, y_2) = (2, 3):
= (3 - 1)/(2 - -4)
3 - 1 = 2:
= 2/(2 - -4)
-(-4) = 4:
= 2/(2 + 4)
2 + 4 = 6:
= 2/6
The gcd of 2 and 6 is 2, so 2/6 = (2×1)/(2×3) = 2/2×1/3 = 1/3:
Answer: = 1/3
