If y varies directly as x and y=7 when x=5 what is the value of y when x=15

y=21 when x =15

Step-by-step explanation:

Since you multiply 5 by 3 to get 15, you also multiply 7 by 3. Therefore y=21

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.

unless if u could do my questions, if not i wouldn't want to
