x and y intercepts

Front

What is an x-intercept?

Back

The x-intercept is the point where a graph intersects the x-axis, meaning the value of y is zero at that point.

Front

What is a y-intercept?

Back

The y-intercept is the point where a graph intersects the y-axis, meaning the value of x is zero at that point.

How do you find the x-intercept of a linear equation?

Back

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

How do you find the y-intercept of a linear equation?

Back

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

Front

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

Back

The x-intercept indicates the value of x at which the output (y) is zero, showing where the function crosses the x-axis.

Front

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

Back

The y-intercept indicates the value of y when x is zero, showing where the function crosses the y-axis.

Front

Given the equation 3x + y = 5, what is the y-intercept?

Back

The y-intercept is (0, 5).

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 relationship between the x-intercept and the slope of a line?

Back

The x-intercept can help determine the slope of a line when combined with the y-intercept.
