First, get the equation into Ax + By = C.
y = \(\frac{-4}{5}\) x - 7 (ADD 7 TO BOTH SIDES)
7 + y = \(\frac{-4}{5}\) x (SUBTRACT y FROM BOTH SIDES)
7 = \(\frac{-4}{5}\) 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 ^-^
