Finding y-intercept

Front

What is the y-intercept?

Back

The y-intercept is the point where a line crosses the y-axis. It occurs when x = 0.

Front

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

Back

To find the y-intercept from a linear equation in the form y = mx + b, the y-intercept is the value of b.

Front

What does the y-intercept represent in a graph?

Back

The y-intercept represents the value of y when x is zero, indicating the starting point of the line on the y-axis.

Front

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

Back

It means that when x = 0, the value of y is 3.

Front

What is the y-intercept of the equation y = 2x + 4?

Back

The y-intercept is 4, as it is the constant term when x = 0.

Front

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

Back

The y-intercept is -2, as it is the constant term when x = 0.

Front

If the y-intercept is -3, what does this indicate on a graph?

Back

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

Front

How can you determine the y-intercept from a table of values?

Back

Look for the row where x = 0; the corresponding y-value is the y-intercept.

Front

What is the y-intercept of the equation y = 5?

Back

The y-intercept is 5, as this is a horizontal line where y is always 5.

Front

If a line crosses the y-axis at (0, 7), what is the y-intercept?

Back

The y-intercept is 7.
