Fill in the other coordinate for the line 2x - 5y = 11: (4, )
enot [183]
2x - 5y = 11.              (4, a).  x = 4, y = a

Substituting into 2x - 5y = 11

2(4) - 5(a) = 11

8 - 5a = 11

-5a = 11 - 8

-5a = 3

a = 3/-5 = -3/5 =- 0.6

Other coordinate =  -3/5 = -0.6

Alex777 [14]
You would use a 5 by 6 tile because you would find a common factor of 24 and 20 which is 4.

24 divided by 4 is 6
20 divided by 4 is 5

So the tiles used to cover the stone would be 6 by 5 tiles

Hope this helps :)
