Given slope-intercept line equation form is .

According to subtraction property of equality: Subtract x from each side.

       (Commutative property of addition: )

                (Additive inverse property: )

                  (Additive identity property: )

           (Divide both sides 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) = .
