Find the Y intercept y = 1/2x - 3

b=

Disclaimer: When I use the EX: 1/2x it means its a fraction and the x is supposed to be in the middle the fraction for those who don't understand it.

How do you find the equation of line of best fit? urgent

Identify a1 and r for the geometric sequence an= -256(-1/4) n-1

Asequence has its first term equal to 4, and each term of the sequence is obtained by adding 2 to the previous term. if f(n) represents the nth term of the sequence, which of the following recursive functions best defines this sequence? (1 point) f(1) = 2 and f(n) = f(n − 1) + 4; n > 1 f(1) = 4 and f(n) = f(n − 1) + 2n; n > 1 f(1) = 2 and f(n) = f(n − 1) + 4n; n > 1 f(1) = 4 and f(n) = f(n − 1) + 2; n > 1 i will award !
