What is the y-intercept of a graph?

Back

The y-intercept is the point where the graph intersects the y-axis, represented as (0, b) where b is the value of y at that point.

Front

What is the slope of a linear equation?

Back

The slope is a measure of the steepness of a line, calculated as the change in y divided by the change in x (rise/run).

What is the Standard Form of a linear equation?

Back

The Standard Form of a linear equation is represented as Ax + By = C, where A, B, and C are integers.

Front

How do you identify the slope from the equation y = mx + b?

Back
