Finding x- and y- intercept

Front

What is the x-intercept?

Back

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

Front

What is the y-intercept?

Back

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

Front

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

Back

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

Front

What is the ordered pair for the x-intercept?

Back

The ordered pair for the x-intercept is of the form (x, 0).

Front

What is the ordered pair for the y-intercept?

Back

The ordered pair for the y-intercept is of the form (0, y).

Front

Back

Set y = 0: 0 = 2x + 4. Solving gives x = -2. The x-intercept is (-2, 0).

Front

Back

Set x = 0: y = -3(0) + 6. The y-intercept is (0, 6).

Front

What does the x-intercept represent in a real-world context?

Back

The x-intercept can represent a point where a quantity reaches zero, such as the break-even point in business.

Front

What does the y-intercept represent in a real-world context?

Back

The y-intercept can represent the initial value of a quantity before any changes occur.
