Front

What is a proportional relationship?

Back

A proportional relationship is a relationship between two quantities where the ratio of one quantity to the other is constant.

Front

How do you identify the slope in a linear equation?

Back

The slope in a linear equation of the form y = mx + b is represented by 'm'. It indicates the steepness of the line.

Front

What is the y-intercept in a linear equation?

Back

The y-intercept is the value of 'y' when 'x' is 0 in the equation y = mx + b. It is represented by 'b'.

Front

How do you calculate the height of a scale model?

Back

To calculate the height of a scale model, divide the actual height by the scale factor.

Front

What is a discount?

Back

A discount is a reduction in the original price of an item, often expressed as a percentage.

Front

If a rectangle measures 4 inches by 6 inches, what are the dimensions of a proportional rectangle with a width of 2 inches?

Back

The dimensions would be 2 inches by 3 inches.

Front

What is the formula for calculating slope between two points (x1, y1) and (x2, y2)?

Back

The formula for slope is (y2 - y1) / (x2 - x1).

Front

What is the relationship between the slope and the steepness of a line?

Back

A larger slope value indicates a steeper line, while a smaller slope value indicates a flatter line.
