I need help with this, I am very lost.​

Remmi wrote the equation of the line y=⅓(x+2) he solved for x and got x=3y-2 which of the following is an equivalent equation for x? a. x=y-11/3 b. x=y+7/3 c. x=3(y-⅔) d. x=3(y+⅔)

What are the solutions of the system? solve by graphing. y = -x^2 -6x - 7 y = 2

Rewrite the following quadratic functions in intercept or factored form. show your work. y = 9 + 12x + 4x^2
