How do you do the slope on a graph

I can't be entirely sure what you want to "do" about the slope,
but here is how to FIND it if you have the line on the graph:

-- You pick two points on the graph line.

-- Find the difference in 'y' between the two points.

-- Find the difference in 'x' between the two points.

-- The slope of the line between the two points is

(the difference in 'y')
divided by
(the difference in 'x') .

-- If the line on the graph is a straight line, then
the slope is the same everywhere on it.

The graph of f(x) = 3.2x-3 is shown below. g(x) is a transformation of f(x).

WINSTONCH [101]

Answer:

C. g(x) = 3·2^x +2

Step-by-step explanation:

The graph of g(x) appears to be a translation upward of the graph of f(x).

To find the equation of g(x), we can add 5 to f(x), since the translation appears to be 5 units. (The y-intercept of f(x) is 0; the y-intercept of g(x) is 5.)

g(x) = f(x) +5

g(x) = (3·2^x -3) +5

g(x) = 3·2^x +2

You can also determine the correct choice by looking at the value at x=0:

A. g(0) = 3 +6 = 9

B. g(0) = 1 +3 = 4

C. g(0) = 3 +2 = 5 . . . . matches g(0) on the given graph

D. g(0) = 3
