Y=mx+b solve for b

Question

I would appreciate if you really helped me thank you 

Answer 1

Gen, y=mx + b, Solve the equation for b means whatever operation done on one side of the equation has to be done on the other side of the equation.  For example let's subtract mx from both sides of the equation: So:  b=y-mx.

Answer 2

Subtract mx on both sides.

 

y - mx = b
