​

Answer 1

Answer:

helo guys its your answer

Step-by-step explanation:

If the three points (-3,7)(a,1)(- 3,2) are collinear then the ... \sf \dfrac{1}{2} \ times [ \ (-3 \times -1 )+(a

As we know that slope of 2points=(y2-y1)/(x2-x1)

Therefore, (2–4)/{a-(-3)}=(-1-2)/(7-p)

»-2/(p+3)=-3/(7-p) by cross multiplication we get

»-2(7-p)=-3(p+3)

»-14+2p=-3p-9

»2p+3p=-9+14

»5p=5,

p=5/5, p=1 Ans
