Question

I don't get how to make y=-4/5x-7 in standard form using integers

Answer 1

First, get the equation into Ax + By = C.

y =
`(-4)/(5)` x - 7 (ADD 7 TO BOTH SIDES)
7 + y =
`(-4)/(5)` x (SUBTRACT y FROM BOTH SIDES)
7 =
`(-4)/(5)` x - y (MULTIPLY BOTH SIDES BY -5)
-35 = 4x + y
^^^^^That's PURE Standard Form^^^^^^^^^
In step 4, you could have multiplied by 5, but A has to be non-negative for this to be PURE standard form. Hope this helps ^-^
