A rectangle that is 2 inches by 3 inches has been scaled by a factor of 7.
What are the side lengths of the scaled copy?
14 inches by 21 inches, because 2⋅7=14 and 3⋅7=21.

Quadrilateral A has side lengths 5, 6, 7, and 8. Quadrilateral B is a scaled copy of Quadrilateral A with a scale factor of 3.
What would be two side lengths for these figures?
A.15
B.24

A rectangle has a scaled copy that is half of it's size. What has happened to the angles in the reduction?
Nothing, the angles are exactly the same.
The angle measurement is the same, the only thing that has changed is the size and the original has been divided by 2.

Jake and Lisa are standing at one corner of a rectangular soccer field looking at the diagonally opposite corner. Jake says that if the field were half as long and half as wide, then it would be half the distance to the far corner. Lisa says that it would be more than half as far, since the diagonal is even longer than the side lengths.
Do you agree with either of them?
What is Jake is right.

If the slope is 1/4, and it goes through the points (4,4) and (8,5), could (9,3) be a point on this line?
No, using the others would make it 1/5 and the other point would be 2/1... they are not the same, and neither are a slope of 1/4.

Elena drank 3 liters of water yesterday. Jada drank 3/4 times as much water as Elena. Lin drank twice as much water as Jada.
Did Jada drink more or less water than Elena?
How do you know?
1.She drank LESS water.
2. Because multiplying by a fraction less than 1 makes a number smaller.
