Interpreting Slope and Y-Intercept

The slope represents the rate of change between two variables on the graph.

It means that for every 1 unit increase in the x-variable, the y-variable increases by 2 units.

The y-intercept is the value of y when x is 0, representing the starting point of the line on the y-axis.

A negative slope indicates that as one variable increases, the other variable decreases.

'm' represents the slope of the line.

'b' represents the y-intercept of the line.

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

A slope of 0 indicates a horizontal line, meaning there is no change in y as x changes.

It means that for every 1 unit increase in the x-variable, the y-variable also increases by 1 unit.

A steep slope indicates a strong relationship, meaning a small change in x results in a large change in y.
