1. y-6= (1-2)
2. y+6= f (x+3)
3. y-2 = -3 (1-6)
4. y-5= -2, (x +9)

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.
