1 is A - just plug and chug
2 is B - for 2 linear equations to have infinite solutions they mustbe the same
3 is C
4 is C - that is where they intersect
5 is A - same slope and different intercepts means no solutions

Is (1,2) a solution of 6x-y>3

tangare [24]

Answer:

Yes

Step-by-step explanation:

To determine if (1, 2 ) is a solution of the inequality, substitute the coordinates into the inequality and if satisfied then they are a solution, that is

(6 × 1) - 2 = 6 - 2 = 4 > 3

Since 4 > 3 then (1, 2 ) is a solution
