Answer 1

Answer:

In first question we are given that

y = 3x

And have to check that (2 , 6) is on line y = 3x or not

Since

When x = 2 then

y = 3(2) = 6

This implies that

(2 , 6) is the solution of the line y = 3x so it means it is on the line y = 3x

In the second question

we have to have answer that weather y = k is parallel to x-axis or not

Since

y = k

means that

y is always is constant it does not matter when is x and so y = k for some integer k this implies that y = k is the equation of line which is parallel to x-axis.
