Answer:
in standard form - y+12x=78
in slope intercept form - y=-12x+78
Explanation:
standard form
13=1/6y+2x
multiply both sides by 6
78=y+12x
y+12x=78
slope intercept
13=1/6y+2x
subtract 1/6y from both sides
13-1/6y=2x
subtract 13 from both sides
-1/6y=2x-13
change the signs on both sides of the equation
1/6y=-2x+13
divide both sides by 1/6
y=-12x+78
