Front

How do you calculate slope using a graph?

Back

Slope is calculated as rise over run.

Front

Back

The graph will show a line with a slope of -rac{2}{3} and a y-intercept of 4.

Back

The slope is -rac{3}{2}.

Front

Define slope in mathematical terms.

Back

Slope is the measure of the steepness of a line, calculated as the change in y over the change in x.

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 formula for calculating slope between two points (x1, y1) and (x2, y2)?

Back

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

Front

What is the significance of the y-intercept in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis.
