Front

What is the y-intercept of a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis, represented as (0, y).

Front

What is the slope in a linear equation?

Back

The slope (m) indicates the rate of change of y with respect to x.

Front

How do you identify a negative slope in an equation?

Back

A negative slope means that as x increases, y decreases. For example, in y = -3x - 5, the slope is -3.

How can you find the y-intercept from a graph?

Back

The y-intercept can be found by locating the point where the line crosses the y-axis.

Front

What is the formula for a linear equation in slope-intercept form?

Back

The formula is y = mx + b, where m is the slope and b is the y-intercept.
