Hoe do u find the other coordinates???

#

And also what does the a=9 imply about the graph

To find the coordinates when theyre both integers think carefully about what x ^2 must be

#

Ie a factor

Idk

#

Ohh

dire fern
#

So what does that make x

#

1 and 3

#

And -1

#

And -3

#

So in order for both y and x to be integers x^2 must be a factor of 9

#

Since x must be also integer we figure out x^2 must be 1 or 9

#

And they have 2 solutions each a positive and negative

#

Use the x to find a corresponding y and thats it
