Answer:
x-2y = -12
Explanation:
Standard form of a line is in the form Ax + By = C where A is a positive integer
y − 3 = 1/2(x + 6)
Multiply each side by 2 to eliminate the fractions
2(y-3)= 1/2*2 (x+6)
Distribute
2y -6 = x+6
Subtract x from each side
-x +2y -6 = x-x +6
-x+2y -6 = 6
Add 6 to each side
-x+ 2y -6+6 = 6+6
-x +2y = 12
Multiply each side by -1 to make A a positive integer
x-2y = -12
