Answer:

x=-3

Step-by-step explanation:

4/x=8/(x-3)

We can solve this using cross products

4 ( x-3) = 8x

Distribute

4x -12 = 8x

Subtract 4x from each side

4x-4x-12 = 8x-12-4x

-12 =4x

Divide each side by 4

-12/4 = 4x/4

-3 =x

b is your yintercept [write it as a point   (0,b) ]
Step 1: Plot the y intercept (0,3)
Step 2: Trace slope from yintercept ... go 2 place up them 1 place right you should end up on the point (5,1)
