proportional relationships
what is this in numbers, for every one yellow sock you have 2 green socks
1:2
These are whole numbers and their opposites, like positive counting numbers, negative counting numbers, and zero.
What are integers?
A mathematical phrase that has numbers, variables, and operations but no equal sign is called this.
What is an expression?
A statement that compares two expressions using symbols like <, >, ≤, or ≥ is called this.
What is an inequality?
This is the amount of space inside a flat shape, like a rectangle or triangle.
What is area?
In the equation y=mx, this letter is used for the constant of proportionality.
What is m?
This is the distance a number is from zero on a number line, always written as a non‑negative value.
What is the absolute value?
A letter or symbol that represents an unknown value is called this.
What is a variable?
This inequality symbol means “greater than or equal to.”
What is ≥?
The distance around a polygon, like a rectangle, is called this.
What is perimeter?
In a proportional relationship, this point, written as (0,0), is always on the graph.
What is the Origin
Numbers that can be written as a fraction of two integers, with a nonzero denominator, belong to this set.
What are rational numbers?
A mathematical statement that shows two expressions are equal is called this.
What is an equation?
The set of all values that make an inequality true is called this.
What is the solution set?
A triangle with one angle equal to a right angle is called this kind of triangle.
What is a right triangle?
When y is proportional to x, this is the ratio you can use to find the constant of proportionality.
What is y/x?
These two numbers have the same distance from zero but are on opposite sides of the number line.
What are opposites?
In an expression, terms that have the same variable raised to the same power are called this.
What are like terms?
On a number line, a filled-in (closed) circle usually means the inequality uses one of these symbol
What are ≤ or ≥
This term describes two figures that have the same shape but not necessarily the same size.
What is similar?
This word describes a relationship where the ratio between x and y stays the same, and the graph is a straight line through the origin.
What is a proportional relationship?
When you add a number and its opposite, this is always the result.
What is zero?
The rule that lets you rewrite a(b+c)ab+ac is called this property.
What is the distributive property?
On a number line, an open circle usually means the inequality uses one of these symbols.
What are < or >?
A quadrilateral with exactly one pair of parallel sides is called this.
What is a trapezoid?
