A. Is the answer

Step-by-step explanation:

a)-2.8/-2 = 4.2/3 is the answers in usa prep test

Step-by-step explanation:

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

ur very much welcome

if y=4x then you will substitute 4x in for y in the second equation.

8x + 4x = 18 combine like terms

12x = 18 divide by 12 on both sides

x = 18/12 or 3/2

now replace x in the first equation with 3/2 to get

y = 4 3/2

y = 6

the answer is a

(3/2,6)

hope that .
