Given slope-intercept line equation form is .

Apply subtraction property of equality: Subtract x from each side.

       (Apply commutative property of addition: )

             (Apply additive inverse property: )

                  (Apply additive identity property: )

            (Divide each side by 2)

                (Cancel common terms)

                   (Divide: )

Slope-intercept line equation form is .

The line equation in slope-intercept form is y = mx + b,

where m is the slope and b is the y-intercept.

Then commpire the slope-intercept line equations.

Slope (m) = , y-intercept (b) = 3.

The solution of slope (m) = .
