Given Coordinates: x1 = -1 y1 = -1, x2 = 2 y2 = -3
Slope Formula: m =
Substitute the given coordinates into the Slope Formula and Simplify:m =
m =
Therefore, the Slope of a Line given points (-1, -1) and (2, -3) is equal to –
Note: As a decimal number, –
Slope Formula: m =
y2 − y1/x2 − x1
Substitute the given coordinates into the Slope Formula and Simplify:m =
-3 − (-1)/2 − (-1)
m =
-3 + 1/2 + 1
m = -2/3
m = – 2/3
Therefore, the Slope of a Line given points (-1, -1) and (2, -3) is equal to –
2/3
Note: As a decimal number, –
2/3
