First find the slope.
We know these two points are in the line: (0,8) and (6,5)
The slope is -1/2. The y-intercept can be found when x = 0. And we know that the point (0,8) is on the line and x = 0, therefore the y-intercept is 8.
Plugging this into the slope-intercept form which is
y = mx + b, where m is the slope and b is the y-intercept, we get:
y = (-1/2)x + 8

Answer:
Third option.
Step-by-step explanation:
Some transformations for a function f(x), are:
If , the function is shifted down "k" units.
If , the function is shifted up "k" units.
If , and
, the functio is stretch vertically by a factor of "b".
If , the function is reflected over the x-axis.
Therefore, knowing that the parent function was transformated by reflecting it over the x-axis, stretching vertically by a factor of 2 and shifting it down 3 units, we can determine that the following function represents the transformation:
