What is the definition of slope in mathematics?

Back

Slope is a measure of the steepness or incline of a line, typically represented as the ratio of the vertical change to the horizontal change between two points on the line.

Front

If two lines are parallel, what can be said about their slopes?

Back

If two lines are parallel, they have the same slope.

Front

What does it mean for two triangles to be similar?

Back

Two triangles are similar if their corresponding angles are equal and their corresponding sides are in proportion.

Front

What is the relationship between the slopes of similar triangles?

Back

The slopes of similar triangles are equal.

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 is the slope of a horizontal line?

Back

The slope of a horizontal line is 0.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined.

Front

What happens to the slope if a line is reflected over the x-axis?

Back

The slope of the line will change its sign; if the original slope is m, the new slope will be -m.

Front

What is the significance of the slope-intercept form of a linear equation?

Back

The slope-intercept form, y = mx + b, allows you to easily identify the slope (m) and the y-intercept (b) of the line.
