If y = 2/3x+4, find y if a. x=0 b. x=3 c. x=-9 d. x= 1\2 plz answer as fast as possible i will be giving y’all all my points plzzz i need the answer

Remark

You should use brackets just to make sure that the x is multiplied by 2/3 and is not some like 2/(3x). Having made the assumption that that is not what you meant I'll  answer this the way I have written it.

y = (2/3) * x + 4

A

x =0

y = (2/3) * 0 + 4

y = 4

B

x = 3

y = (2/3) * 3 + 4  The threes cancel out leaving you with 2 as the first number after the equal sign on the right.

y = 2 + 4

y = 6

C

x = - 9

y = (2/3)(-9) + 4

y = 2 (-3) + 4  

y = - 6 + 4 Think money. If you are 6 dollars in the hole and someone give you 4 dollars you are now only 2 dollars in the whole.

y = - 2

D

y = (1/2)*(2/3 + 4   The twos cancel out

y = 1/3 + 4

y = 4 1/3 = 13/3 or 4.33333. It depends on what your marker expects.

the first domain and range set to the left is matched with the top relation, and the second set the set in the middle goes with the bottom relation.
