Look at this function:

x y
−6 −13
−4 −9
−2 −5
0 −1

mark said that the function is linear.

jason said that the function is nonlinear.

which of the following explains who is correct?

As x coordinate of function is : -6, -4, -2, 0

And y coordinate of function is : -13, -9, -5,-1

If a function is linear it means

Slope will be same everywhere.

Slope between two points is =

=

So, between any two points slope are same i.e equal to 2.So it is a linear function.

So, Mark is right that the function is linear.

360/29
