Find the b (y-intercept)

Front

What is the y-intercept?

Back

The y-intercept is the point where a line crosses the y-axis on a graph.

Front

How do you find the y-intercept from a graph?

Back

To find the y-intercept, look for the point where the line intersects the y-axis. This point has coordinates (0, b), where b is the y-intercept.

Front

What does the y-intercept represent in a linear equation?

Back

In a linear equation of the form y = mx + b, the y-intercept (b) represents the value of y when x is 0.

Front

If a line crosses the y-axis at (0, 3), what is the y-intercept?

Back

The y-intercept is 3.

Front

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

Back

The y-intercept is 1.

Front

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

Back

The y-intercept is 2.

Front

If a line has a y-intercept of -2, what does this mean?

Back

It means the line crosses the y-axis at the point (0, -2).

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 = 0.5x - 4?

Back

The y-intercept is -4.

Front

If the y-intercept is 0, what does this indicate about the line?

Back

It indicates that the line passes through the origin (0, 0).
