y= -1.4x-6.6

Step-by-step explanation:

(1,-8)

7x+5y=-7

Make the equation into standard form

Subtract 7x from both sides

5y=-7x-7

Divide all by 5

y=-1.4x-1.4

Since they are parrallel, we know the slope is -1.4x

y=-1.4x+b

(1,-8) is one of the points it goes through

Replace the x and y in the equation for the x and y in the incomplete equation

-8=-1.4+b

Add 1.4 to both sides

-6.6=b

Thus the equation is

y=-1.4x-6.6

The answer to your question is:  letter A and letter B

Step-by-step explanation:

A   1,000 mL = 1 L     This option is correct, there are 1000 ml in 1 liter.

B   1 g = 100 cg          This option is correct, there are 100 cg in 1 gram.

C   1,000 km = 1 m   This option is incorrect, the proportion is 1000 meters in

                                  1 kilometer.
