3. Solving for a Variable

Exercise 3 Page 57

Isolate m using inverse operations.

m=y-b/x

Practice makes perfect

We are asked to use the formula for the slope-intercept form to write an equation for m. We will use inverse operations to isolate the variable. First we will isolate mx by subtracting b from both sides of the equation.

y=mx+b

LHS-b=RHS-b

y-b=mx

.LHS /x.=.RHS /x.

y-b/x=m

Rearrange equation

m=y-b/x
