Identifying y-intercepts

Front

What is the y-intercept?

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 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, identify the value of b.

Front

What does the slope (m) represent in a linear equation?

Back

The slope (m) represents the rate of change of y with respect to x. It indicates how steep the line is.

Front

In the equation y = 2x + 3, what is the y-intercept?

Back

The y-intercept is 3.

Front

In the equation y = -x + 5, what is the y-intercept?

Back

The y-intercept is 5.

Front

If a line has a slope of 0, what can you say about its y-intercept?

Back

If a line has a slope of 0, it is horizontal and the y-intercept is the constant value of y.

Front

What is the y-intercept of the line represented by the equation y = 4?

Back

The y-intercept is 4, as the line is horizontal.

Front

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

Back

The y-intercept can be determined by locating the point where the line crosses the y-axis.

Front

What is the y-intercept of the equation y = 3x - 2?

Back

The y-intercept is -2.

Front

If the equation of a line is given as y = 0.5x + 1, what is the y-intercept?

Back

The y-intercept is 1.
