x and y intercepts

Front

What are x and y intercepts?

Back

The x-intercept is the point where a graph crosses the x-axis (y=0), and the y-intercept is where it crosses the y-axis (x=0).

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.

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.

What is the x-intercept of the equation 2x - 5y = 1?

Back

Set y=0: 2x = 1, so x = 0.5. The x-intercept is (0.5, 0).

Front

What is the y-intercept of the equation 2x - 5y = 1?

Back

Set x=0: -5y = 1, so y = -0.2. The y-intercept is (0, -0.2).

Front

What does the y-intercept represent in a graph?

Back

The y-intercept represents the value of y when x is zero, indicating where the line crosses the y-axis.

What does the x-intercept represent in a graph?

Back

The x-intercept represents the value of x when y is zero, indicating where the line crosses the x-axis.

Front

Identify the x-intercepts of the graph with points (-4, 0) and (4, 0).

Back

The x-intercepts are -4 and 4.

Front

What is the significance of the point (0, b) in a linear equation?

Back

The point (0, b) represents the y-intercept of the line, where b is the value of y when x is zero.

What is the significance of the point (a, 0) in a linear equation?

Back

The point (a, 0) represents the x-intercept of the line, where a is the value of x when y is zero.
