Well, since these are rectangles, and both have 2 measurements, it would be quite simple, you must find how 9 and 15 are similar, then see if that same similarity is found within the 3 and the 5. the answer is yes, they are similar because... 9×1 1/3=15 and 3× 1/3=5 therefore they are similar. hope this helped, plz follow me
Well if you use graph paper you can graph the points you already have and then you can find the slope of the line easiest that way, the next point would be. (-1,8)
