Finding Slope Practice

Front

What is the formula to find 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, meaning the line rises 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, meaning the line falls from left to right.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined.

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0.

Front

How do you identify the slope from the slope-intercept form of a line (y = mx + b)?

Back

The slope (m) is the coefficient of x in the equation.

Front

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

Back

The slope is 3.

Front

If the slope of a line is -4, what does this tell you about the line's direction?

Back

The line falls from left to right.

Front

How do you find the slope from a graph?

Back

Choose two points on the line, calculate the rise (change in y) and run (change in x), then use the formula slope = rise/run.

Front

What is the slope of the line that passes through the points (2, 3) and (4, 7)?

Back

The slope is 2.
