Answer:

y = -2x - 1

Step-by-step explanation:

If two lines are parallel, then they must have the same slope but different y-intercepts.

Original line: y = -2x + 7

If we need to find a line parallel to this one, then that line has to have the same slope which is -2. This means you can eliminate B and C.

Now, the new line also has to pass through (0, -1). In order to find out which line is parallel, you have to plug in the coordinate points to its respective places for answer choices A and D.

Choice A:

y = -2x + 6

-1 = -2(0) + 6

-1 = 6

So, the answer is not A. Let's try D.

Choice D:

y = -2x -1

-1 = -2(0) - 1

-1 = -1

So, the answer is choice D.

Two garden plots are to have the same area. One is square and one is rectangular. The rectangular plot is 2 meters wide and 8 me

Crank

First, let's look at the formulas for the area of square and area of the rectangle.

$A_{square}=a^2$

$A_{rectangle}=a\cdot b$

And what this exercise states is that the areas are the same. So:

$A_{square}=A_{rectangle}\Longrightarrow a^2=a\cdot b$

Now put in the data.

$a^2=2\cdot8$

Solve for $a$ :

$a=\sqrt{2\cdot8}=\sqrt{16}=\boxed{4}$

The side of the square garden plot is 4 meters.

Hope this helps.
