Slope/y-intercept

Front

What is the formula for calculating the slope of a line?

Back

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

Front

What does the slope of a line represent?

Back

The slope represents the rate of change of y with respect to x.

Front

How do you determine if a slope is positive or negative?

Back

A positive slope rises from left to right, while a negative slope falls from left to right.

Front

What is the y-intercept in the equation y = mx + b?

Back

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

Front

How can you find the slope from a graph?

Back

Slope is calculated as rise over run.

Front

What does 'rise' refer to in the context of slope?

Back

Rise refers to the vertical change between two points on a line.

Front

What does 'run' refer to in the context of slope?

Back

Run refers to the horizontal change between two points on a line.

Front

If a line has a slope of 0, what does that indicate about the line?

Back

A slope of 0 indicates a horizontal line.

Front

If a line has an undefined slope, what does that indicate about the line?

Back

An undefined slope indicates a vertical line.

Front

What is the relationship between the slope and the angle of a line?

Back

The slope is the tangent of the angle that the line makes with the positive x-axis.
