Question

A linear graph contains the points of (-10,4), (-8,2), (-6,0), (-4,-2), (0,-6), (2,-8). Is the function of the graph y = -x - 6?

Answer 1

Yes, it is.

Explanation:

`y=-x-6` implies `x+y=-6` i.e. the sum of ordinate and abscissa is `-6`

As in all the given points,

`(-10,4), (-8,2), (-6,0), (-4,-2), (0,-6), (2,-8)`

the sum of ordinate and abscissa is `-6`,

these represent the linear relation `y=-x-6`
graph{-x-6 [-16.25, 3.75, -4.2, 5.8]}
