y - 2 = -3 (x+1)
point slope form
y-y1 = m(x-x1)
looking at the above equation
the slope is -3
It is not differentiable at x=1 since the slope of the tangent line as x -> 1 from the right is 1 while the slope of the tangent line as x->1 from the left is -1
It's an octagon.
The sum of the measures of the angles in the polygon with n sides:
S = 180°(n - 2)
n = 8
S = 180°(8 - 2) = 180° · 6 = 1080°
Answer: 1080°
Any scale factor less than 1 would show that an image has been reduced, or contracted, when compared to the original.
