The formula for simple interest is I = Prt, where I is the interest earned, P is the principal, r is the interest rate and t is the number of years. Solve the formula for r in
terms of P, I and t.
Solve for r?

step-by-step explanation:

; fx

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. : )
