Suppose aequals=qr where r is an invertible matrix. show that a and q have the same column space. [hint: given y in col a, show that yequals=qx for some x. also, given y in col q, show that yequals=ax for some x.] if y is in col a, then which of these is true?

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
