Given Coordinates: x1 = -1 y1 = 4, x2 = 3 y2 = -8
Slope Formula: m =
Substitute the given coordinates into the Slope Formula and Simplify:m =
m = -3
Therefore, the Slope of a Line given points (-1, 4) and (3, -8) is equal to -3
Slope Formula: m =
y2 − y1/x2 − x1
Substitute the given coordinates into the Slope Formula and Simplify:m =
-8 − 4/3 − (-1)
m = -8 − 4/3 + 1
m = -12/4
m = – 12/4
(Greatest Common Factor of 12 and 4, GCF(12, 4) = 4)m = -3
Therefore, the Slope of a Line given points (-1, 4) and (3, -8) is equal to -3
