Introduction to Slope review

Front

What is the formula to calculate the slope of a line?

Back

Slope (m) = (y2 - y1) / (x2 - x1)

Front

Find the slope of the line that passes through the points (2, 3) and (4, 7).

Back

Slope = 2

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that as x increases, y also increases.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that as x increases, y decreases.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined.

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0.

Front

If a line has a slope of 0, what can be said about its graph?

Back

The graph of the line is horizontal.

Front

If a line has a slope of -1/4, what does this tell us about the line's steepness?

Back

The line is gently sloping downwards.

Front

What is the slope of the line that passes through the points (-1, 2) and (3, 2)?

Back

Slope = 0 (horizontal line)
