Answer:

y=3x-3

Step-by-step explanation:

The equation of the line with the slope m and passing through the point (x_0,y_0) is

y-y_0=m(x-x_0)

In your case,

m=3\\ \\x_0=3\\ \\y_0=6

Hence, the equation of the line is

y-6=3(x-3)\\ \\y-6=3x-9\\ \\y=3x-9+6\\ \\y=3x-3

inna [77]

Answer:

D

Step-by-step explanation:

The function F(x) = \frac{1}{3}*4^x has value F(2) when x = 2 is substituted.

F(x) = \frac{1}{3}*4^x\\F(2) = \frac{1}{3}*4^2\\F(2) = \frac{1}{3}*16\\F(2) = \frac{16}{3}
