Question

How do you right -6x-42=-16y in standard form?

Answer 1

16y=6x+42
16/16y=6x/16+42/16
y= 3x/8 + 21/8 

Answer 2

In standard form, do you mean slope?

If you do, this is what I got;
y= 6/16x - 2.625
In the slope, the negative cancels out because both the numerator and the denominator are negative.
