Finding x and y-intercepts

Front

What is a y-intercept?

Back

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

Front

What is an x-intercept?

Back

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

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

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

True or False: The x-intercept occurs where y is equal to zero.

Back

True

Front

What is the ordered pair for the y-intercept of the equation 2x + 3y = 6?

Back

(0, 2) - Set x = 0, then solve for y.

Front

What is the ordered pair for the x-intercept of the equation 4x + y = 8?

Back

(2, 0) - Set y = 0, then solve for x.

Front

What does the point (0, 5) represent on a graph?

Back

It represents the y-intercept, where the graph crosses the y-axis.

Front

What does the point (5, 0) represent on a graph?

Back

It represents the x-intercept, where the graph crosses the x-axis.

Front

If a line has a y-intercept of (0, 3), what does this mean?

Back

It means the line crosses the y-axis at the point (0, 3).
