Does the residual plot show that the line of best fit is appropriate for the data?
Yes, the points have no pattern.
O Yes, the points are evenly distributed about the x-
axis.
O No, the points are in a linear pattern.
O No, the points are in a curved pattern.

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
