We included HMH Into Math Grade 5 Answer Key PDF Module 19 Review to make students experts in learning maths.

Vocabulary

Question 1.
Draw lines to match the description to the term.

Explanation:
An ordered pair is a composition of the x coordinate and the y coordinate (ordinate),
having two values written in a fixed order within parentheses.
example:(5, 2)
5 is the x-coordinate number and 2 is the y-coordinate number.

Concepts and Skills

Question 2.
Which point is located at (5, 2)?

(A) point A
(B) point B
(C) point C
(D) point D
point D
Explanation:
(5, 2) is located as point D.
in order pair 5 represent the x coordinate and 2 represent the y coordinate.

Question 3.
Three vertices of a rectangle are located at (8, 5), (6, 5), and (6, 2). Graph the rectangle. Where is the fourth vertex located? What is the perimeter?

Explanation:
perimeter = 2(l + b)
p = 2 (3 + 2)
p = 2 x 5
p = 10 units.
Fourth vertex is located at (8,2)

Question 4.
Use Tools What is the distance between the points (5, 3) and (5, 5)? Tell what strategy or tool you will use to solve the problem, explain your choice, and then find the answer.

Explanation:
I have used the coordinate plot
distance from first order pairs to the next order pairs.

Question 5.
Point A has coordinates (3, 4). Point B is 2 units farther from the y-axis than point A. Which ordered pair represents the coordinates of point B?
(A) (3, 2)
(B) (3, 6)
(C) (1, 4)
(D) (5, 4)
Explanation:

(5, 4) is 2 units from the y-axis
(3, 4) and (5, 4) is pointed on the coordinate grid.

Question 6.
In the graph, what could the point located at (6, 3) represent?

Explanation:
On day 6th he read 3 hours
that is pointed as day on x-axis and hours on y-axis.

Question 7.
Chelsea and Melissa are writing number patterns. Chelsea starts at 0 and uses the rule “Add 2, then multiply by 2.” Melissa starts at 2 and uses the rule “Add 4,” Select all of the ordered pairs in which the x-coordinate represents a number in Chelsea’s pattern and the y-coordinate represents the corresponding number in Melissa’s pattern.
(A) (2, 0)
(B) (0, 2)
(C) (12, 10)
(D) (24, 14)
(E) (60, 18)
(B) (0, 2)
(C) (12, 10)
(E) (60, 18)
Explanation:
These are the order pairs which we get when we follow the pattern rules
Chelsea starts at 0 and uses the rule “Add 2, then multiply by 2.” Melissa starts at 2 and uses the rule “Add 4,”
(0 , 2) adding 2 to 0 and multiplying 2 gives 4 and adding 4 to 2 gives 6
so, the next order pair is (4, 6) than (12, 10) as on.

Question 8.
For every 2 tablespoons of butter, Sasha uses 3 tablespoons of flour for her sauce. Complete the table and graph the ordered pairs. What appears to be the relationship between the amounts of butter and flour?
