non linear

ajspeller · Answer

Linear functions have a constant slope.  Apply the slope formula to several order pairs and if they are the same then its linear.

... Why non linear

anonymous · Answer

because each of the x and y is not the same on top and bottom.

tukitw · Answer

Don't understand...

tukitw · Answer

I'm pretty sure you will get a straight line/linear if you plot it though

anonymous · Answer

x	−2	0	1	3	4
y	4	8	10	14	16
so the -2 to the 0 is +2 the 0 to the 1 is +1 so they arent the same which equal non linear.
