# What is b in y=mx+b?

## Answer: b is the y-intercept of the line.

**Explanation:**

The equation of a straight line is ax +by = c

we can rewrite the above equation in terms of y and it is called slope-intercept form.

The general equation of a line in slope-intercept form is y=mx+b

where b is called the y-intercept and m is the slope.
