Problem

Specify the residual plot for inputs \(2,~4,~6,~8\) and residuals \(0.5,~-0.5,~1,~-1\), using \(x~\text{from}~2~\text{to}~8~by~2\), \(\text{residual}~y~\text{from}~-1~\text{to}~1~by~0.5\), and a \(\text{zero}\) line. Give the points, count, sign totals, and pattern note.

Answer choices

Choose your path.

Preview only

points=(2,-0.5),(4,0.5),(6,-1),(8,1); count=4; zero line y=0; above=2,on=0,below=2; pattern note=every residual sign is negated

points=(2,2),(4,4),(6,6),(8,8); count=4; zero line y=0; above=4,on=0,below=0; pattern note=inputs are plotted against themselves

points=(0.5,2),(-0.5,4),(1,6),(-1,8); count=4; zero line y=0; above=2,on=0,below=2; pattern note=coordinates are swapped

points=(2,0.5),(4,-0.5),(6,1),(8,-1); count=4; zero line y=0; above=2,on=0,below=2; pattern note=signs alternate around zero
