If `(x, y), (a, 0), (0, b)` are collinear, then using determinants prove that `x/a + y/b = 1` .

If points (a ,0),\ (0, b)a n d\ (x , y) are collinear, using the concept of slope prove that x/a+y/b=1.

If the points (a, 0) (0, b) and (x, y) are collinear, then

If the points A(x,y), B(a,0) and C(0,b) are collinear, prove that (x)/(a) + (y)/(b) = 1

If points (a,0),(0,b) and (x,y) are collinear, using the concept of slope prove that (x)/(a)+(y)/(b)=1

If the points (x,y),(a,0) and (0,b) are collinear, prove that x/a + y/b = 1, ab ne 0

If the points (0,0),(1,2) and (x,y) are collinear then :

If the points (p,0), (0,q)and (x,y) are collinear, prove that x/p+y/q= 1 .

If the points (2,0),(0,5) and (x,y) are collinear then show that x/2+y/5=1 .

If the equations 2x + 3y + 1 = 0,3x + y - 2 = 0 , and ax + 2y-b = 0 are consistent then prove that a - b = 2 .
