At point (3, 10)

x = 3, and y = 10

Then


3x-y=3(3)-10=9-10=-1\\e10

Therefore (3, 10) is not a solution to the equation.

At point (4, -2)

x = 4, and y = -2.

Then


3x-y=3(4)-(-2)=12+2=14\\e10

Therefore (4, -2) is not a solution to the equation.

Hence,

neither point is a solution

Option A is the correct choice
