Hello.
Let's use the slope formula in order to find the slope:
Where
y₂ = the y-coordinate of the second point (-6)
y₁=the y-coordinate of the first point (6)
x₂=the x-coordinate of the second point (11)
x₁=the x-coordinate of the first point (7)
Plug in the values:
Therefore, m (the slope) is equal to -3.
I hope it helps.
Have an outstanding day. :)
