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. At this point, 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. At this point, 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 = 0 in the equation and solve for x.

Front

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 line has an x-intercept of (4, 0), what does this mean?

Back

It means that the line crosses the x-axis at the point where x = 4.

Front

If a line has a y-intercept of (0, 3), what does this mean?

Back

It means that the line crosses the y-axis at the point where y = 3.

Front

What is the x-intercept of the equation y = 2x - 8?

Back

Set y = 0: 0 = 2x - 8; x = 4. So, the x-intercept is (4, 0).

Front

What is the y-intercept of the equation y = 2x - 8?

Back

Set x = 0: y = 2(0) - 8; y = -8. So, the y-intercept is (0, -8).
