suppose you have a regression line from a scatter plot of six points. what residual value is missing, if you have the residual values of 2.35, 1.7, 3.2, 1.2, and −4.5?

a) 2.95

b) 3.95

c) −2.95

d) −3.95

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.
