The predicted change in mass of the puppies each day. So the first option.
Answer:
Option D.
Step-by-step explanation:
Consider the below figure attached with this question.
From the below figure it is clear that the coordinates of given points are A(-4,0), B(2,-3) and C(-2,2).
Slope of line AB is
The slope of two parallel lines are same.
So, the slope of required line is -1/2.
The point slope form of a line is
where, m is slope.
The equation of required line is
Substitute y=0 in the above equation to find the x-intercept of required line.
The x-intercept of required line is (2,0). Therefore, the correct option is D.

Answer:
y = -x-3
x-y = -3
x - 2y = 10
Step-by-step explanation:
x − 3y = 6
Slope intercept form is y = mx +b
We need to solve for y
Subtract x from each side
x-x-3y = -x+6
-3y = -x +6
Divide each side by -3
-3y/-3 = -x/-3 +6/-3
y = 1/3 x -2
Standard form is Ax +By = C
y = -x-3
Add x to each side
x-y = -x+x-3
x-y = -3
y = 1/2x -5
We do not like fractions in standard form, so multiply by 2
2y = 2*1/2x -2*5
2y =x-10
Subtract x from each side
-x +2y = x-x-10
-x+2y = -10
We like to have the coefficient on x be positive
Multiply by -1
x - 2y = 10

Answer: Choice A</h3>
Arrow from 0 to -8 (pointing left). Another arrow from -8 to -6 (pointing right)
See diagram below
================================================================
Explanation:
Let's think of this in terms of money. Writing -8 means we are 8 dollars in debt. Since -8 is listed first, this means we start at 0 and go 8 units to the left along the number line, to land on -8.
Then we'll go 2 units to the right to land ultimately at -6. This is because of the "-(-2)" portion, which is the same as "+2". Subtracting a negative is the same as adding. The two negatives cancel each other out.
Going back to the money example, if we have a balance of -8 (we're 8 dollars in debt) and taking away 2 IOU notes means we're 6 dollars in debt. Subtracting a negative can be thought of as taking away debt.
Side note: If we had -8-2, then we would go 2 units to the left of -8 to land on -10 instead.
