Answer:
In the equation y+4=3(x-3), we can see that x and y are the variables and 4 and -3 are the constants.
To convert the equation to the form Ax + By = C, we'll first distribute the 3 on the right side:
y + 4 = 3x - 9
Next, we'll move all the terms with x to one side of the equation and all the terms with y to the other side:
-3x + y = - 13
Now we have the equation in the form Ax + By = C, where A = -3, B = 1, and C = -13.
