Need help step by step​

Y = mx + b

8x - 4y - 9 = 0

first you move the nine to the other side of the equal sign (add nine to both sides)

8x - 4y = 9

then you need to also move your 8x over to the other side as well (remember we are trying to get y by itself!)

- 4y = -8x + 9

then we are going to divide -4 to both sides

and you get

y = 2x - 9/4

we can then identify the slope as 2

so B. 2 would be your answer

hope this helped

X/8=8/64 Solve the proportion for x.
Alexxandr [17]

Answer: x = 1

Step-by-step explanation:

Step 1: Cross-multiply.

x/8 = 8/64

x*(64)=(8)*(8)

64x=64

Step 2: Divide both sides by 64.

64x/64 = 64/64

\frac{64x}{64} =\frac{64}{64} \\

Therefor, the answer is x = 1

* Hopefully this helps:) Mark me the brainliest:)!!
