QuestionBrian sets up the distance formula to find the length, dd, of the line segment. His work is shown. What error, if any, did Brian make? d=(x2(31))2+(y1(01)2d=\sqrt{\left(x_{2}-\left(-3_{1}\right)\right)^{2}+\left(y_{1}-\left(0_{1}\right)^{2}\right.} A. He subtracted the coordinates instead of adding them to get the distance terms. B. He incorrectly found dd, instead of d2d^{2}. C. The point he chose to draw the legs of the triangle does not form a right angle. D. He incorrectly squared each distance term

Studdy Solution
Identify the error:
- The notation 31-3_{1} and 010_{1} is incorrect. It seems like there is a misunderstanding or typographical error in the subscript usage. - The expression (y1(01)2(y_{1}-(0_{1})^2 is incorrectly structured. It should be (y2y1)2(y_2 - y_1)^2.
The error Brian made is related to the incorrect notation and structure of the distance formula. The correct choice is:
D. He incorrectly squared each distance term
