Please help me solve this equation 2x+y=10

krek1111 [17]

This is the answer
$2x + y = 10 \\ y = - 2x + 10$

if substitute 1 and 2 and 3 as x then the points will be :
$\binom{x}{y} \: \: \: \: \: \: \binom{1}{8} \: \: \: \: \: \: \binom{2}{6} \: \: \: \: \: \: \binom{3}{4}$

and that's the picture

good luck
