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: )
(Add 2 to each side)
(Apply additive inverse property: )
(Apply additive identity property: )
(Add: )
The equation of the line is .
