Answer:
y = -3/7x + 5
Move the slope and x value on the left side.
y = -3/7x + 5
3/7x + y = 5
That is basically the standard form.
But if the answer is not applicable, try moving 5 to the left side too and the right side would be 0 (this is plan B).
3/7x + y - 5 = 0
But the most used standard form is the first one
