Consider the points P(3,−2) and Q(−1,4) in the coordinate plane.
(i) Find the slope of the line passing through P and Q.
(ii) Using your result from part (i), obtain the equation of the line in slope–intercept form.
(iii) Rewrite the same equation obtained in part (ii) in the general form Ax+By+C=0, clearly mentioning the values of A,B and C.
