Slope Flashcard

Front

What is the slope of the line represented by the equation y = ⅓ x + 1?

Back

The slope (m) is ⅓.

Front

What is the y-intercept of the line y = 4x - 10?

Back

The y-intercept (b) is -10.

Front

In the equation y = (3/2)x + 3, what are the slope and y-intercept?

Back

The slope (m) is 3/2 and the y-intercept (b) is 3.

Front

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

Back

The formula is (y2 - y1) / (x2 - x1).

Front

Define slope in simple terms.

Back

Slope is defined as rise/run.

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 slope from a graph?

Back

To find the slope from a graph, select two points on the line, determine the rise (change in y) and run (change in x), and use the formula rise/run.
