Math STAAR Review - Graphing

A worker is building toys at a factory. The relationship between the number of hours the employee works, x, and the number of toys the employee builds, y, is represented by the equation y = 9x. Which graph represents this relationship?

• 
• 
• 
• 

The points plotted on the coordinate grid represent the rule

y = x + 5.

Which table also represents this rule?

• 
• 
• 
• 

Which table contains only x-values and y-values that make the equation y = 4.8x true?

• Table F

• Table G

• Table H

• Table J

A pet store owner will order dog beds for his shop. The relationship between x, the number of boxes he will order, and y, the number of dog beds he will receive, can be represented by the equation y = 12x.

Which table contains only values that represent the equation?

• Table A

• Table B

• Table C

• Table D

Which table of values does NOT represent y = x + 4.5

• Table F

• Table G

• Table H

• Table J

Elsa and a group of her friends always sit together at lunch. Every

day students join them at the table where they sit. The table below

shows the relationship between the number of students joining Elsa

and her friends and the total number of students sitting at the

table.

The type of relationship that exists between the number of

students joining and the total number of students at the table is —

• an additive relationship, because the pattern is to add 5 to the

  number of students joining in order to get the total number of

  students at the table

• a multiplicative relationship, because the total number of

  students at the table is greater than the number of students

  joining

• an additive relationship, because the number of students joining

  is less than the total number of students at the table

• a multiplicative relationship, because the pattern is to multiply

  the number of students joining by 5 in order to get the total

  number of students at the table

The table shows x-values and y-values for a number pattern.

Which statement is true?

• The pattern is multiplicative, because the y-values are 1.5 times the

  corresponding x-values.

• The pattern is multiplicative, because the y-values are 6 more than the

  corresponding x-values.

• The pattern is additive, because the y-values are 1.5 times the corresponding

  x-values.

• The pattern is additive, because the y-values are 6 more than the corresponding

  x-values.

Which answer choice best describes the x-coordinate in an ordered pair?

• The horizontal line composed of the set of points that all have a

  y-coordinate of O

• The first number in an ordered pair that determines the

  movement left or right from the origin on a coordinate grid

• The second number in an ordered pair that determines the movement up or down from the origin on a coordinate grid

• The intersection of two lines on a coordinate grid

Which statement is NOT true about a coordinate grid?

• The vertical number line is the y-axis.

• In a coordinate grid, the x-axis and the y-axis are perpendicular to each other.

• The x-coordinate is the second number in an ordered pair.

• The origin is the intersection of the x-axis and the y-axis.

Carmella plotted the ordered pair (1, 3) on a coordinate grid by

moving 1 unit up and 3 units left from the origin. Which statement

is true?

• Carmella plotted the x-coordinate incorrectly and the

  y-coordinate correctly.

• Carmella plotted both the x-coordinate and the y-coordinate

  correctly.

• Carmella plotted the x-coordinate correctly and the y-coordinate

  incorrectly.

• Carmella plotted both the x-coordinate and the y-coordinate

  incorrectly.
