Proportional Tables and Graphs

Front

What is a coordinate point?

Back

A coordinate point is a pair of numbers that define a specific location on a graph, represented as (x, y).

Front

What does it mean for a table to be proportional?

Back

A proportional table shows a constant ratio between two quantities, meaning as one quantity increases, the other increases at a consistent rate.

Front

How do you determine if a graph is proportional?

Back

A graph is proportional if it passes through the origin (0,0) and forms a straight line.

Front

What is the formula for finding the slope of a line?

Back

The slope (m) is calculated as m = (y2 - y1) / (x2 - x1).

Front

What is the total cost if one ticket costs $75 and there are 7 adults?

Back

The total cost is $525.

Front

What is a non-proportional relationship?

Back

A non-proportional relationship does not maintain a constant ratio between two quantities.

Front

How can you identify a proportional relationship in a table?

Back

If the ratios of corresponding values are equal, the relationship is proportional.

Front

What does the y-intercept represent in a graph?

Back

The y-intercept is the point where the line crosses the y-axis, indicating the value of y when x is 0.

Front

What is the difference between independent and dependent variables?

Back

The independent variable is the one that is changed or controlled, while the dependent variable is the one that is measured or affected.

Front

What is an example of a proportional relationship in real life?

Back

An example is the relationship between distance and time when traveling at a constant speed.
