Slope

Front

What is the definition of slope?

Back

Slope is a measure of the steepness or incline of a line, typically represented as the ratio of the vertical change to the horizontal change between two points on the line.

Front

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

Back

The formula for slope (m) is m = (y2 - y1) / (x2 - x1).

Front

What type of slope is represented by a line that rises from left to right?

Back

Positive slope.

Front

What type of slope is represented by a line that falls from left to right?

Back

Negative slope.

Front

What type of slope is represented by a horizontal line?

Back

Zero slope.

Front

What type of slope is represented by a vertical line?

Back

Undefined slope.

Front

Calculate the slope between the points (3, 4) and (7, 10).

Back

Slope = (10 - 4) / (7 - 3) = 6 / 4 = 3/2.

Front

If a line has a slope of 0, what does that indicate about the line?

Back

The line is horizontal.

Front

If a line has an undefined slope, what does that indicate about the line?

Back

The line is vertical.

Front

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

Back

The slope is 2.
