X and Y Intercepts

Front

What is the x-intercept?

Back

The x-intercept is the point where a line crosses the x-axis. At this point, the y-coordinate is 0.

Front

What is the y-intercept?

Back

The y-intercept is the point where a line crosses the y-axis. At this point, the x-coordinate 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.

Given the ordered pair (9,0), what does it represent?

Back

(9,0) represents the x-intercept of a line.

Front

Given the ordered pair (0,-5), what does it represent?

Back

(0,-5) represents the y-intercept of a line.

Front

What are the x- and y-intercepts of the line represented by the equation y = 2x - 10?

Back

x-intercept: (5,0), y-intercept: (0,-10).

Front

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

Back

The x-intercept indicates where the output (y) is zero, showing the value of x at that point.

Front

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

Back

The y-intercept indicates where the input (x) is zero, showing the value of y at that point.

Front

If a line has an x-intercept of (4,0), what does this tell us?

Back

It tells us that the line crosses the x-axis at x = 4.
