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 value of y is 0.

Front

What is the y-intercept of a graph?

Back

The y-intercept is the point where the graph crosses the y-axis, meaning the value of x is 0.

Front

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

Back

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

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

Back

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

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 are the x- and y-intercepts of the equation y = 2x - 6?

Back

The x-intercept is (3, 0) and the y-intercept is (0, -6).

Front

How can you graph a line using intercepts?

Back

Plot the x-intercept and y-intercept on the graph, then draw a line through these two points.
