Plzz thnaksss are these correct? ?

The first picture is correct, the triangle was dilated by a factor of 1/3 and then shifted 2 units down.

The second picture is also correct, because the dots are higher as they move to the right, it is a positive association and they follow a linear line.

√(2.x²/18) = x√(2/9) = x√(1/3)² = x.1/3 = x/3
