Given Coordinates: x1 = 2 y1 = 4, x2 = -1 y2 = 9
Slope Formula: m =
Substitute the given coordinates into the Slope Formula and Simplify:m =
Therefore, the Slope of a Line given points (2, 4) and (-1, 9) 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 =
9 − 4/-1 − 2
m = 5/-3
m = – 5/3
Therefore, the Slope of a Line given points (2, 4) and (-1, 9) is equal to –
5/3
Note: As a decimal number, –
5/3
≈ -1.6666666666667
