Slope = change in y / change in x
= (8 - -3) / (1 - 2) = (8 + 3) / ( 1 - 2)
= 11 / -1
= -11
Slope is negative.
51% less.
The length is decreased by 50%, which is the same as being multiplied by 0.5, then it's increased by 40% which is another multiplication by 1.4. So the overall change is 0.5 * 1.4 = 0.7, or the newest rectangle is 70% of the size of the original rectangle. And since the area increases by the square, the newest rectangle has 0.7 * 0.7 = 0.49 of the area as the original rectangle. So it has 51% less area than the original rectangle.
Positive sine, negative tangent, means we have a negative cosine. We're talking about the second quadrant.
We know it's negative,
Answer: -(1/3)√5
