What is the equation of a line in slope-intercept form?

Back

The equation of a line in slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

What does the slope of a line represent?

Back

The slope of a line represents the rate of change of the output value (y) with respect to the input value (x).

What is the y-intercept in a linear equation?

Back

The y-intercept is the value of y when x is 0, representing where the line crosses the y-axis.

Front

How can you determine the slope from a table of values?

Back

The slope can be determined by finding the change in y divided by the change in x between two points.

What is the relationship between tables, graphs, and equations?

Back

Tables provide numerical data, graphs visually represent that data, and equations describe the relationship mathematically.
