2 and 7 that is how you will get your answer
Since this equation has infinite solutions (each pair is a point on the line with equation x-6y=6), you can choose an arbitrary value for x, say 0, and deduce y:

So, (0,1) is an ordered pair (x,y) that is a solution to the equation x-6y=6.
You can repeat this process with every possible x value, and solve for the correspondent y value and find infinite pairs.
Answer:

Answer:
f(3) =19
Step-by-step explanation:
f(x)=2x^2+1
Let x = 3
f(3) = 2(3)^2 +1
Exponents first
=2(9) +1
Then multiply
=18+1
=19
