X^2 + 8x - 4 = 0 by Completing The Square

a framing bias

step-by-step explanation:

rodrigo is subject to a framing bias i believe.

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. : )

part a: 1.08

part b: 27.59
