Which ordered pair would form a proportional relationship with the point graphed below?

On a coordinate plane, a line with negative slope goes through points (negative 20, 10), (0, 0), and (20, negative 10).
(10, –20)
(–30, 20)
(–10, 5)
(35, –20)

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!
