Question

solve for m.
$y = mx + b$
$m = \frac{y - b}{x}$ $m = y - b - x$
a b
$m = \frac{x}{y - b}$ $m = yx - b$

Explanation:

Step1: Isolate $mx$ term

Subtract $b$ from both sides:
$y - b = mx$

Step2: Solve for $m$

Divide both sides by $x$ ($x
eq 0$):
$\frac{y - b}{x} = m$

Answer:

A. $m = \frac{y-b}{x}$
