What is the definition of a linear equation?

Back

A linear equation is an equation that makes a straight line when graphed, typically in the form y = mx + b, where m is the slope and b is the y-intercept.

What is the meaning of the term 'y-intercept'?

Back

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

Front

If a graph shows a constant increase, what can be said about its slope?

Back

The slope is positive, indicating that as x increases, y also increases.
