Step-by-step explanation:
i looked it up for you
Determine the slope - down 1, right 3. This is -1/3.
Determine the y-intercept. Up 3 from the origin.
Use this information to form an equation:

The answer is 2.84375 because multiplying
4x-y=-20
Subtract 4x and bring it to the other side
-y=-4x-20
Divide by -1
Y= 4/1+20/1 which = y=4x+20
