Gien the points
G ( -2 , 6 )
H ( 5, -3 )
x1= -2
x2 = 5
y1 = 6
y2 = -3
Determine the slope of GH.
Formula for the slope of the line:
m = change in y/ change in x
m = (y2 - y1)/(x2 - x1)
Solution:
Substitute the given values to the formula for the slope of the line.
m = (y2 - y1)/(x2 - x1)
m = (- 3- 6)/(5 - (-2))
m = (-3 - 6)/(5 + 2)
m = (-9)/7
m = -9/7
Final answer:
The slope of the line = -9/7
