176 = a1 * r^4
704 = a1 * r^6

dividing:-

r^2 = 706/174 =  4   so r = +/- 2

a1 =  176 / 2^4 =  176/16 = 11

So 11 is the first term

Y = x - 1
romanna [79]

Answer: The correct answer is the third option, (-3,-4).

Step-by-step explanation: You plug in 2x + 2 for y, given that y = 2x + 2.

2x+2 = x - 1

x = -3

Now, you plug in -3 for x in an equation.

y = -3 - 1

y = -4.

(-3, -4)
