IF YOUR GOOD AT MATH THEN PLEASE ANSWER THIS ASAP Which equation represents standard form for a linear equation?

1: y − y1 =m(x − x1)
2: Ax +By = C
3: y = mx + b

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
