Intro to Finding Slope Flashcard

Front

What is the slope formula?

Back

The slope (m) of a line passing through two points (x1, y1) and (x2, y2) is calculated using the formula: m = (y2 - y1) / (x2 - x1).

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that as the x-value increases, the y-value also increases, meaning the line rises from left to right.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that as the x-value increases, the y-value decreases, meaning the line falls from left to right.

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.

Back

The slope is 2.

Front

Find the slope of the line that passes through the points (1, 2) and (3, 6).

Back

The slope is 2.

Front

Find the slope of the line that passes through the points (0, 0) and (5, 5).

Back

The slope is 1.

Front

Find the slope of the line that passes through the points (1, 1) and (1, 4).

Back

The slope is undefined.

Front

What is the slope of the line represented by the equation y = 3x + 2?

Back

The slope is 3.
