Web9 jan. 2024 · Therefore, either 'y should be negative and (x+y) should be positive' or 'y should be positive and (x+y) should be negative'. Statement 1: X > 0. No info about y so not sufficient. Statement 2: Y < 0. No info about x so not sufficient. Both together, we know that y is negative. We now need to know the sign of (x+y). WebStep Two: Substitute Into the Distance Formula. Now that we have x1,y1,x2, and y2, we can substitute these values into the Distance Formula. d=√ (x2−x1)2+ (y2−y1)2=√ (−2−3)2+ (15−7)2=√ (−5)2+ (8)2=√25+64=√89.
