x & y intercepts

Front

What are x and y intercepts?

Back

The x-intercept is the point where a graph crosses the x-axis (y=0), and the y-intercept is where it crosses the y-axis (x=0).

How do you find the x-intercept of an equation?

Back

To find the x-intercept, set y=0 in the equation and solve for x.

Front

What does the slope represent in a linear equation?

Back

The slope (m) represents the rate of change of y with respect to x; it indicates how steep the line is.

What is the significance of the y-intercept in a graph?

Back

The y-intercept (b) indicates the value of y when x=0; it is the point where the line crosses the y-axis.
