Sonji plots –9 on a number line to represent the depth of her sailboat underwater and labels it b. she plots positive 20 on the same number line to represent the height of her sailboat above water and labels it a. sonji asks if b, the elevation below sea level, acts as an opposite to a, the elevation above sea level. what is the best answer to her question?

  No.

Step-by-step explanation:

The opposite of a number is that number with its sign changed. The opposite of A is -20, not -9.

parallel and congruent

step-by-step explanation:

the movement of translation is linear.   these have the same translation because you are using the same rule for each point of the triangle so you will see the same slope being used to get from a point on the triangle to its image.

same slope!   you should think parallel when you see those 2 word together (well unless it's the same line but it can't be because we are coming from different points here)

congruent! because each point is being moved the same distance.

a rotation about point l
