How do you solve for b in #y = mx + b#?

Answer 1

Abigail Allen

Subtract #color(red)(mx)# from each side of the equation to solve for #b#:

#y - color(red)(mx) = mx - color(red)(mx) + b#

#y - mx = 0 + b#

#y - mx = b#

#b = y - mx#

To solve for ( b ) in the equation ( y = mx + b ), you need to isolate ( b ) on one side of the equation.

You can do this by subtracting ( mx ) from both sides of the equation:

[ y - mx = b ]

So, ( b = y - mx ).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
