4. Find Slope from Two Points

Front

What is the formula to find the slope between two points?

Back

The slope (m) is calculated using the formula: m = \frac{y_2 - y_1}{x_2 - x_1}.

Front

What does a slope of 0 indicate about a line?

Back

A slope of 0 indicates that the line is horizontal.

Front

What does an undefined slope indicate about a line?

Back

An undefined slope indicates that the line is vertical.

Front

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

Back

The slope is 0.

Front

Calculate the slope between the points (5, -2) and (5, -7).

Back

The slope is undefined.

Front

Calculate the slope between the points (5, 10) and (8, 12).

Back

The slope is \frac{2}{3}.

Front

What is the significance of the slope in a linear equation?

Back

The slope indicates the steepness and direction of the line.

Front

If the slope is positive, what does that tell you about the line?

Back

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

Front

If the slope is negative, what does that tell you about the line?

Back

A negative slope indicates that the line falls from left to right.

Front

What are the coordinates of the first point in the slope formula?

Back

(x_1, y_1) are the coordinates of the first point.
