Answer: The campers will be 
from their car after 12 hours.
Step-by-step explanation:
<h3>
The missing graph is attached.</h3>
The equation of the line in Slope-Intercept form is:
Where "m" is the slope and "b" the y-intercept.
We can pick two points on the line graphed and substitute the coordinates into this formula to find the slope:
Choosing the points (0,4) and (2,10), we get:
We can susbstitute the point (0,4) and the slope into and solve for "b":
Then, the equation of this line is:
Since the distance in miles is represented on the y-axis and the time in hours is represented on the x-axis. we can rewrite the equation as:
Finally, in order to calculate the distance in miles that the campers will be from their car after 12 hours, we need to subsitute 
into the equation and evaluate. Then we get:
The equation of line passing through the point P(-8,0) that is perpendicular to the line y=-3 is y=0 which can be found out from slope intercept formula.
It is given to us that -
The point is P(-8,0)
The line is represented as y=-3
The point P is perpendicular to the given line.
We have to find out the equation of the line passing through P which is perpendicular to the given line.
We know that the equation of a line is given by -
y = mx + c
where, (x, y) = coordinates of the point
m = slope of the line
c = a constant
Comparing this with the equation of the given line, we have
m=0 and c =-3
This implies that the slope of the perpendicular is also equal to 0.
The slope intercept formula for the perpendicular line can be represented as -
y = mx + c
Using the coordinates of P(-8,0), we have
0 = 0*(-8) +c
=> c = 0.
Thus, the equation of line passing through the point P(-8,0) that is perpendicular to the line y=-3 is y=0.

Answer:
Integers are the set of whole numbers and their opposites. Whole numbers greater than zero are called positive integers. Whole numbers less than zero are called negative integers.
X^2+y^2-8x+4y+4=0 can be written as (<span>x- 4)² + (y+2)²-16-4+4=0, or
</span> (<span>x- 4)² + (y+2)²=16, this is not a an equation of parabola, it is a circle's
</span>its center is (4, -2) and its radius r=4
