Help I don't understand it

Rectangle Z is not a scale drawing of Rectangle Y.

This is because there is no equal sides where it makes up the constant proportionality.

6/4 (= 3/2) in the left and right sides of the rectangle (Y/Z)

4/3 in the top and bottom sides of the rectangle (Y/Z)

As you can see 3/2 is not equal to 4/3 of scaling, so therefore it is not a scaling.

both graphs increase on their domain

neither graph has a y-intercept

step-by-step explanation:

the following points can be visualized easily from the graph
