Identify 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 y-coordinate is zero. It is represented as (x, 0).

What is the y-intercept of a graph?

Back

The y-intercept is the point where the graph crosses the y-axis, meaning the x-coordinate is zero. It is represented as (0, y).

Front

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

Back

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

Front

Identify the x-intercept of the equation 2x + 3y = 6.

Back

(3, 0) - Set y = 0: 2x = 6, x = 3.

Front

Identify the y-intercept of the equation 2x + 3y = 6.

Back

(0, 2) - Set x = 0: 3y = 6, y = 2.

Front

What does the point (0, 0) represent on a graph?

Back

The point (0, 0) is the origin, where the x-axis and y-axis intersect.

Front

What is the significance of the x-intercept in real-world applications?

Back

The x-intercept can represent a point where a quantity reaches zero, such as profit or population.

Front

What is the significance of the y-intercept in real-world applications?

Back

The y-intercept can represent the starting value of a quantity when the independent variable is zero.

Front

Given the points (0, -4), (1, 3), and (4, 0), identify the y-intercept.

Back

(0, -4) - The y-intercept is where x = 0.
