Given point is and slope(*m*) = 3.

Because you know the slope and a point on the line,

Use point - slope form to write an equation of the line.

Let = and slope(*m*) = 3.

(Substitute 2 for ,4 for and *m* = 3)

Rewrite in slope - intercept form.

(Product of two same signs is positive)

(Apply distributive property: )

(Multiply: )

Apply addition property of equality: If *a* = *b* then *a* +* c* = *b *+ *c*.

(Add 2 to each side)

(Apply additive inverse property: )

(Apply additive identity property: )

(Add: )

The equation of the line is .
