Question

If the point (1,4) , (3,y) and (-3,16) are collinear then the value of Y will be​

Answer 1

the point (1,4) , (3,y) and (-3,16) are collinear,

so,

$\frac{y - 4}{3 - 1} = \frac{16 - y}{ - 3 - 3} \\ = > \frac{y - 4}{2} = \frac{16 - y}{ - 6} \\ = > y- 4 = \frac{16 - y}{ - 3} \\ = > 3y + 12 = 16 - y \\ = > 4y = 4 \\ = > y = 4$

SO THE VALUE OF Y IS 4
