Consider the following causal model y bx + v; x cy + u; where b 6 = 0; c 6 = 0 and bc 6 = 1: Suppose that the values of (u; v) are generated from (U; V ) s N 0; uu uv uv vv : We do not observe (U; V ) but we could observe the equilibrium solution (X, Y ). (a) Consider the special case with uu = 0 but vv 6 = 0 so that the model becomes

the answer to the question is a

step-by-step explanation:

it has the same slope and the same y-intercept.

y + 11 = -7/9(x - 18)

y + 11 =-7/9x + 14

b

y = -7/9x + 3

y-intercept (0, 3)

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
