y = −1/4x^2 + 4x − 19

1. Use x = -b/2a to find x.

x = -4/2(-1/4)

x = -4/(-1/2)

x = -4/1 • (-2/1)

x = 8/1

x = 8

2. Plug x into the function to find your vertex.

Replace every x you see in the function with 8 and do the math.

Take it from here.

-4x - 6 = -5y + 9 y=
xxMikexx [17]

Answer:

y =4/5x + 3

Step-by-step explanation:

−4x−6=−5y+9

Step 1: Flip the equation.

−5y+9=−4x−6

Step 2: Add -9 to both sides.

−5y+9+−9=−4x−6+−9

−5y=−4x−15

Step 3: Divide both sides by -5.

−5y/−5

=

−4x−15/−5

y=

4/5x+3

Answer:

y=

4/5x+3
