Slope Flashcard

Front

Find the slope between the points (1, 2) and (4, 5).

Back

Slope = (y2 - y1) / (x2 - x1) = (5 - 2) / (4 - 1) = 3/3 = 1.

Front

What type of slope does a vertical line have?

Back

Front

What does a negative slope indicate about a line?

Back

The line decreases as it moves from left to right.

Front

What does a positive slope indicate about a line?

Back

The line increases as it moves from left to right.

Front

Find the slope of the line through the points (2, 3) and (5, 7).

Back

Slope = (7 - 3) / (5 - 2) = 4/3.

Front

If the slope of a line is 0, what can be said about the line?

Back

The line is horizontal.

Front
