The equation y = m x + b is the slope-intercept form of the equation of a line. What is the equation solved for b?

Step-by-step explanation:

This is a literal equation. The mx part of the equation is being added to the b, so in order to move it away from b to solve for b we have to undo that addition by subtraction. Subtracting mx from both sides gives us the literal equation solved for b:

y - mx = b
