Using the Property of Equality, what first step would you take to rearrange the formula

Question

$y=mx+b$ using x as the quantity of interest?
Subtract b from both sides of the equation.
Divide both sides by m.
Subtract mx from both sides
Divide both sides byy.

Answer 1

To rearrange the formula \( y = mx + b \) using \( x \) as the quantity of interest, the first step you should take is to subtract \( b \) from both sides of the equation.

This gives you:

\[ y - b = mx \]

After that, you could proceed to isolate \( x \). But the correct first step from the choices provided is to subtract \( b \) from both sides.
