Which of the following line passes through point (-4,5) and is parallel to the line segment whose endpoints are at (-2,-3) and (2,5)?

Answers

For this case we have that by definition, the equation of a line of 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

By definition, if two lines are parallel then their slopes are equal.

Then, the requested line will have a slope equal to:

m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}} = \frac {5 - (- 3)} {2 - (- 2)} = \frac {5 +3} {2 + 2} = \frac {8} {4} = 2

Thus, the line is of the form:

y = 2x + b

We substitute point(-4,5) and find "b":

5 = 2 (-4) + b\n5 = -8 + b\n5 + 8 = b\nb = 13

Finally, the equation is:y = 2x + 13

Answer:

y = 2x + 13

alis dog weighs 8 times as much as her cat. together, the two pets weigh 54 pynds. how much does Alis dog weigh?

Answers

The weight of the Alis dog is \fbox{\bf48} pounds.

Further explanation:

Consider the weight of the Alis dog as xpoundsand weight of the cat as ypounds.

Since, the weight of the Alis dog is 8 times the weight of the cat. It can be written as follows:

x=8y                                                                     ......(1)

Now, the total weight of the cat and dog are given as 54 pounds. It can be written as follows:

x+y=54                                                                 ......(2)

From equation (1), substitute 8y for x in equation (2).

\begin{aligned}8y+y&=54\n9y&=54\ny&=(54)/(9)\ny&=6\end{aligned}

Thus, the weight of the cat is 6 pounds.

Substitute 6 for y in equation (1) to obtain the weight of Alis dog as follows:

\begin{aligned}x&=8(6)\n&=48\end{aligned}

Thus, the weight of the Alis dog is 48 pounds.
