Answer:
1. (4,6)
2. (-1, 8)
3. Not enough information given.
Step-by-step explanation:
1. Reflecting the point over the y-axis will place the point (-4,6) 4 units on the other side of the axis. This would place it at (4,6) without changing the y-coordinate.
2. Reflections across the line y=x means y and x trade places. This will result in the point (8,-1) becoming (-1,8).
3. Not enough information about the shape is given. Need to know where it is now to know where it will go.
Answer:The bar model is a pictorial representation of a problem. In a word problem the bar model helps students to visualize the relationship between the numbers given and what are they looking for. For subtraction ( and addition ) you can use Part - Whole bar model. Whole - Part 1 = Part 2.
Step-by-step explanation:
Let's try all the answers with the above equation
a) 4 as p and -4 as q
4 - 4 = 8? INCORRECT
b) 10 as p and 1 as q
10 - 1 = 8? INCORRECT
c) -4 as p and 4 as q
-4 - 4 = 8? INCORRECT
d) 11 as p and 3 as q
11 - 3 = 8? correct
