Pls help I'm dying ;)

Answer:
1) Subtract x on both sides to get
y = -x + 3
2) Subtract x on both sides to get -3y = -x + 12, then divide by -3 on both sides to get y = 1/3 x - 4
3) Subtract 5x on both sides to get 2y = -5x + 10, then divide by 2 on both sides to get
y = -5/2 x + 5
4) If I'm not mistaken, y = 6x + 1/3 is already in slope-intercept form (y=mx+b).
5)
[tex]y = \frac{1}{x} x - 15[/tex]
This is also in slope-intercept form⤴⤴⤴ It's just going to have a slope of 0, meaning it will be a horizontal line that passes through the y-axis at -15.
Sorry if it's wrong. Hope it helps though :)
