Find slope

Front

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

Back

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

Front

Find the slope of the points (1, 8) and (3, 12).

Back

Slope = 2

Front

Find the slope of the points (-2, 3) and (4, -5).

Back

Slope = -4/3

Front

What type of slope does a line that rises from left to right have?

Back

Positive slope

Front

What type of slope does a line that falls from left to right have?

Back

Negative slope

Front

What is the slope of a horizontal line?

Back

Zero slope

Front

What is the slope of a vertical line?

Back

Undefined slope

Front

Find the slope of the line represented by the equation y = 2x + 3.

Back

Slope = 2

Front

If the slope of a line is 4/3, what does this indicate about the line's steepness?

Back

The line rises 4 units for every 3 units it moves to the right.

Front

How does the slope of a line affect its graph?

Back

The slope determines the angle of the line; steeper slopes indicate a greater change in y for a given change in x.
