For this case we have that by definition, the equation of a line in the slope-intersection form is given by:

y = mx + b

Where:

m: It's the slope

b: It is the cut-off point with the y axis

According to the statement we have the following equation:

$y = - \frac {1} {2} x-4$

The slope is:

$m = - \frac {1} {2}$

By definition, if two lines are parallel then their slopes are equal. Thus, a parallel line will have slope $m = - \frac {1} {2}$ . Therefore, the equation will be of the form:

$y = - \frac {1} {2} x + b$

In the statement they tell us that b = -1, substituting we have:

$y = - \frac {1} {2} x-1$

The equation is:

$y = - \frac {1} {2} x-1$

Step-by-step explanation:

x y

1 2

2 4

3 9

4 16

This sounds like a quadratic equation of f(x)=x^2, thus, the range is:

R(x): (-∞,+∞)If the function only has these points, then the range is:R(x): [2]∪[4]∪[9]∪[16]
