Answers: perpendicular bisector; image
- The reflection of a point P across a line m is the point P' if line m is the <u> perpendicular bisector </u> of segment PP'
- Point P' is called the <u> image </u> of point P.
=============================================================
Explanation:
If we were to reflect point P over line m to land on P', then we've gone from pre-image to image.
Let's say that Q is the point on segment PP' and it's also on line m. We consider Q the midpoint of segment PP' which means PQ and P'Q are the same length. This indicates P and P' are the same distance away from the mirror line, and that point Q bisects segment PP'. Also, line m is perpendicular to segment PP'. So that's where the "perpendicular bisector" comes from.
(0, -3)(2, -2)
slope = (-2 + 3)/(2-0) = 1/2
b = -3

No, a teaspoon is too small to measure the capacity of a milk carton. You would use a quart to measure the capacity of a gallon.
Hope this helps :)
Answer:
1 3/5
Step-by-step explanation:
Anything larger than 1 multiplied by 3 1/4 would result in a number more than 3 1/4.
