line symmetry is a perfect reflection of a shape when cut in half. imagine a line down the shape. its the square, the triangle and the trapizoid.
You can do the normal 12 - 3 = 9
Or 12 + (-3) = 9
The answer to the question is B
2.25 for the first box
5 is the answer under the 11.25 box and it equals 2.25
15.75 is the top answer and it equals 2.25
The constant proportionality is 2.25
y=2.25x
Yes they’re proportional and the equation is y=1.3x
Let me know if that makes sense
