Slope and Slope Intercept Practice

Front

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

Back

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

Front

What does a positive slope indicate about a line on a graph?

Back

A positive slope indicates that as x increases, y also increases, meaning the line rises from left to right.

Front

What does a negative slope indicate about a line on a graph?

Back

A negative slope indicates that as x increases, y decreases, meaning the line falls from left to right.

Front

What is the slope of the line that passes through the points (1, 2) and (4, 5)?

Back

The slope is 1.

Front

What is the y-intercept in the slope-intercept form of a line (y = mx + b)?

Back

The y-intercept (b) is the value of y when x = 0.

Front

What does the slope represent in a real-world context?

Back

The slope represents the rate of change between two variables.

Front

How do you identify the slope from the equation of a line in slope-intercept form?

Back

The slope is the coefficient of x in the equation y = mx + b.

Front

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

Back

The slope is -2.

Front

If a line has a slope of 0, what does that mean?

Back

A slope of 0 means the line is horizontal and does not rise or fall.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined.
