Slope Review

Front

What is the formula to calculate the slope of a line given two points (x1, y1) and (x2, y2)?

Back

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

Front

Find the slope of the line that passes through the points (2, 4) and (6, 12).

Back

Slope = 2

Front

What is the slope of the line represented by the equation y - 3x = 1?

Back

Slope = 3

Front

What is the x-intercept of the line represented by the equation 3x + y = 5?

Back

x-intercept = (-1, 0)

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that the line rises as it moves from left to right.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that the line falls as it moves 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

How do you find the y-intercept of the line represented by the equation 3x + y = 5?

Back

Set x = 0, then y = 5, so the y-intercept is (0, 5).

Front

What is the definition of slope in the context of a graph?

Back

Slope is a measure of the steepness or incline of a line on a graph.
