Answer 1

Answer:

Step-by-step explanation:

If (x,y) , (1,2) and (7,0) are collinear points, then slope of any two points must be same.

So, (y-2)/(x-1) = (0-2)/(7-1)

= (y-2)/(x-1) = (-1/3)

= 3(y-2) = -(x-1)

= 3y - 6 = -x + 1

= x + 3y = 7

Thus , for given points to be collinear, x and y must be related as:

x + 3y = 7
