Question

9x+lly=15 determine if liear​

Answer 1

Answer: Yes, it is.

First you have to subtract X on both sides.

9x-9x+11y=-9x+15

equals

11y=-9x+15 (You cannot combine unlike numbers)

You divide both sides by 11.

11y/11= -9x+15/11

equals

Y= -9/11 X+15/11

Although it doesn't look so, graphing calculators online will show that this answer in linear.
