What is a linear graph?

Back

A linear graph is a graph that represents a linear relationship between two variables, typically in the form of a straight line.

Front

What is an exponential graph?

Back

An exponential graph represents a relationship where a quantity increases or decreases at a constant rate relative to its current value, typically resulting in a curve.

Front

How do you determine if a graph is linear, exponential, or neither?

Back

To determine the type of graph, analyze the rate of change: if it is constant, it is linear; if it increases or decreases at an increasing rate, it is exponential; otherwise, it is neither.

Front

In a word problem, how do you set up an equation based on given relationships?

Back

Identify the relationships described in the problem, assign variables to unknowns, and translate the relationships into an equation.

Front

What is the total number of items if a family receives magazines, letters, bills, and ads with specific relationships?

Back

To find the total, set up an equation based on the relationships and solve for the unknowns.

Front

If angle 1 measures 160 degrees, how do you find the measure of angle 2 if they are complementary?

Back

If angles are complementary, their measures add up to 90 degrees. If they are supplementary, they add up to 180 degrees.

Front

What is the equation for total cost in a word problem involving fixed and variable costs?

Back

The total cost can be expressed in the form y = mx + b, where m is the variable cost per unit, x is the number of units, and b is the fixed cost.

Front

How do you calculate the percentage of a group that shows up for work?

Back

To calculate the percentage, divide the number present by the total number in the group and multiply by 100.

Front

What does 'round to the nearest tenth' mean in a percentage calculation?

Back

Rounding to the nearest tenth means adjusting the number to one decimal place, based on the value of the hundredths place.

Front

What is the relationship between the number of magazines and letters in a word problem?

Back

In the given problem, the number of magazines is equal to the number of letters.
