1. Write three different ratios that would form a proportion with the ratio of
5/3

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
