What is the equation of a line, in general form, that passes through point (1, -2) and has a slope of 1/3.

3x - y - 7 = 0
x - 3y + 7 = 0
x - 3y - 7 = 0

He that is measured at 220° is a reflex angle. the opposite angle is obtuse. find the measure of obtuse .

Suppose that the price p, in dollars, and the number of sales, x, of a certain item follow the equation 4 p plus 4 x plus 2 pxequals56. suppose also that p and x are both functions of time, measured in days. find the rate at which x is changing when xequals2, pequals6, and startfraction dp over dt endfraction equals1.5.
