Identify y-intercept

Front

What is the y-intercept in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis, represented as (0, b) in the equation y = mx + b.

Front

In the equation y = mx + b, what does 'b' represent?

Back

'b' represents the y-intercept of the line.

Front

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

Back

The y-intercept can be found by locating the point where the line intersects the y-axis.

Front

If a line has a y-intercept of -2, what is the value of 'b'?

Back

b = -2.

Front

If a line has a y-intercept of 4, what is the value of 'b'?

Back

b = 4.

Front

If a line has a y-intercept of 1, what is the value of 'b'?

Back

b = 1.

Front

What does it mean if the y-intercept is negative?

Back

A negative y-intercept indicates that the line crosses the y-axis below the origin.

Front

What does it mean if the y-intercept is positive?

Back

A positive y-intercept indicates that the line crosses the y-axis above the origin.

Front

Can a line have a y-intercept of zero?

Back

Yes, if the y-intercept is zero, the line passes through the origin (0, 0).

Front

What is the significance of the y-intercept in real-world scenarios?

Back

The y-intercept can represent the starting value of a situation, such as initial cost or starting population.
