Alg1 Intro To Slope

Front

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

Back

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

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that as x increases, y also increases, resulting in an upward slant from left to right.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that as x increases, y decreases, resulting in a downward slant 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.

Front

Given the points (2, -7) and (-1, 6), what is the slope?

Back

-13/3

Front

Given the points (-2, -9) and (-1, -3), what is the slope?

Back

-6

Front

Given the points (3, 4) and (5, 10), what is the slope?

Front

What are the coordinates of point H if it lies on the line y = 2x + 2 when x = -2?

Back

(-2, 4)

Front

If a line has a slope of -4/3, what type of slope does it have?

Back

Negative slope.
