1: 10, 1: 100, 1: 200 which one is the strongest

I don't know what you mean by the 'strongest', but 1:10 is the greatest in this set of ratios.

because

1:10 is 1 divided by 10, 1:100 is 1 divided by 100, and 1:200 is 1 divided by 200.

if it's divided by a large number, than the number decreases.

y=4x+11

Step-by-step explanation:

Substitute the coordinates in each of the above equations,

Then the left hand side of the equation should be equal to the right hand side of the equation.

By substituting the above coordinates in the second answer,

-1= 4(-3)+11

-1=-1
