Proportions Slope

Front

What is a proportion?

Back

A proportion is an equation that states that two ratios are equal.

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, calculated as the rise over run between two points on the line.

Front

How do you calculate the slope between two points (x1, y1) and (x2, y2)?

Back

The slope (m) is calculated using the formula: m = (y2 - y1) / (x2 - x1).

Front

What does a slope of 0 indicate about a line?

Back

A slope of 0 indicates that the line is horizontal.

Front

What does an undefined slope indicate about a line?

Back

An undefined slope indicates that the line is vertical.

Front

If a line passes through the origin (0,0), what is its slope?

Back

The slope is equal to the constant of proportionality.

Front

What is the constant of proportionality in a proportional relationship?

Back

The constant of proportionality is the slope of the line representing the relationship.

Front

If a line passes through the points (2, 4) and (6, 12), what is the slope?

Back

The slope is 2.

Front

What is the slope of the line that passes through (-3, -18) and (3, 18)?

Back

The slope is 6.

Front

If the slope of a line is 1/2, what does this mean in terms of rise and run?

Back

For every 1 unit of rise, there are 2 units of run.
