Finding Y-Intercept (11:30)

Front

What is the y-intercept of a line?

Back

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

Front

How can you find the y-intercept from an equation in slope-intercept form?

Back

In the equation y = mx + b, the y-intercept is represented by b.

Front

What does the y-intercept represent in a real-world context?

Back

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

Front

If a line has a y-intercept of 5, what does this mean?

Back

It means that when x = 0, the value of y is 5.

Front

What is the y-intercept of the equation y = -3x + 4?

Back

The y-intercept is 4.

Front

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

Back

Locate the point where the line crosses the y-axis; that point's y-coordinate is the y-intercept.

Front

What is the y-intercept of the line represented by the equation y = 2x - 1?

Back

The y-intercept is -1.

Front

If a graph shows a y-intercept of -2, what does this indicate?

Back

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

Front

What is the y-intercept of the equation y = 0.5x + 3?

Back

The y-intercept is 3.

Front

In the equation y = -x + 1, what is the y-intercept?

Back
