x & y intercepts

Front

What is the definition of a y-intercept?

Back

The y-intercept is the point where a graph intersects the y-axis, represented as (0, y).

What is the definition of an x-intercept?

Back

The x-intercept is the point where a graph intersects the x-axis, represented as (x, 0).

Front

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

Back

(0, 3) because when x = 0, y = 3.

Front

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

Back

(-1.5, 0) because when y = 0, x = -1.5.

Front

What is the y-intercept of the line represented by the equation 4x + 2y = 8?

Back

(0, 4) because when x = 0, y = 4.

Front

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

Back

It indicates the value of y when x is zero, showing where the graph starts on the y-axis.
