Answer:

a = 9, b = 3, c = 0

Step-by-step explanation:

f(x) = (1/3)^x

a = f(-2) = (1/3)^-2= 9

b = f(-1) = (1/3)^-1 = 3

c = f(0) = (1/3)^0 = 1

whenever something is to the power of 0, the answer will always be 1

Complete the point-slope equation of the line through (-5,4) and (1,6). Use exact numbers.

BigorU [14]

ANSWER

$y - 6 = \frac{2}{7} (x - 1)$

EXPLANATION

The point-slope equation of a straight line is given by:

$y-y_1=m(x-x_1)$

Where m is the slope.

The line goes through (-5,4) and (1,6).

The slope of this line is,

$m = \frac{6 - 4}{1 - - 6}$

$m = \frac{2}{7}$

The point-slope equation is

$y - 6 = \frac{2}{7} (x - 1)$
