What is -1 - 9
Solve for 2x-4y =20
X=4

So -1-9= -10

And if x =4 then 2(4)-4y=20

Y= -3

Step-by-step explanation:

2(4)-4y=20

8-4y=20

-4y=12

y=-3

-1 - 9 = -10 &

y = -3

Step-by-step explanation:

2x - 4y = 20

2(4) - 4y = 20

8 - 4y = 20

-4y = 12

y = -3

good luck, i hope this helps :)

32

step-by-step explanation:

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
