X and Y intercepts

Front

What is the x-intercept of a graph?

Back

The x-intercept is the point where the graph crosses the x-axis, meaning the y-coordinate is zero.

What is the y-intercept of a graph?

Back

The y-intercept is the point where the graph crosses the y-axis, meaning the x-coordinate is zero.

Front

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

Back

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

How do you find the y-intercept from an equation?

Back

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

Front

What is the significance of the x-intercept in a linear equation?

Back

The x-intercept indicates the value of x when the output (y) is zero, showing where the function starts on the x-axis.

What is the significance of the y-intercept in a linear equation?

Back

The y-intercept indicates the value of y when the input (x) is zero, showing where the function starts on the y-axis.

Front

If a graph has an x-intercept of 3, what does this mean?

Back

It means that the graph crosses the x-axis at the point (3, 0).

Front

If a graph has a y-intercept of -1, what does this mean?

Back

It means that the graph crosses the y-axis at the point (0, -1).

Front

What is the general form of a linear equation?

Back

The general form of a linear equation is Ax + By + C = 0, where A, B, and C are constants.

Front

How can you determine the slope of a line using intercepts?

Back

The slope can be determined by the formula (y2 - y1) / (x2 - x1) using the coordinates of the x-intercept and y-intercept.
