I need help with this please

Choose the point slope form of the equation below that represents the like that passes through the points (-6,4) and (2, 0)

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.

Which point-slope form equation represents a line that passes through (3,-2) with a slope of -4/5
