find y intercept

Front

What is the y-intercept?

Back

The y-intercept is the point where a line crosses the y-axis, represented as (0, y).

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 a positive slope indicate about a line?

Back

Front

If a line has a y-intercept of (0, -1), what does this indicate?

Back

It indicates that the line crosses the y-axis at the point (0, -1), meaning the value of y is -1 when x is 0.
