y = 0.25x + 2
Assuming you require the equation of the line with slope = 0.25 and passing through the point (12, 5 )
the equation of a line in ' slope- intercept form ' is
y = mx + c ( m is the slope and c the y- intercept )
the partial equation is y = 0.25 + c
to find c, substitute (12, 5 ) into the partial equation
5 = 3 + c ⇒ c = 5 - 3 = 2
y = 0.25x + 2 is the equation in point- slope form
