How do you represent a linear relationship in a graph?

Back

A linear relationship is represented by a straight line on a graph, showing how one variable changes in relation to another.

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, calculated as the change in the y-coordinate divided by the change in the x-coordinate.

What is the y-intercept?

Back

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

Front

How do you write the equation of a line in slope-intercept form?

Back

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