Question

In the equation = + , what does b represent?

Answer 1

Although the equation is incomplete (b doesn't appear), I'll venture a guess that the correct equation looks something like this:

y = 2x + b [or y = mx+b]

b is the y-intercept.

Explanation:

In the format of y = 2x + b, b represents the y-intercept (the value of y when x = 0).
