On the graph below, draw any line with a slope of *positive* 2 and draw any line with a slope of *negative* 2.

Elenna [48]

Refer to the image for the graph of the lines.

The common form of the equation of a line is y = mx + c, where m is the slope of the line and c is a constant.

We need to draw any line with a slope m = 2, and

another line with a slope m = -2.

Disclaimer: Let us assume that the constant c = 0.

Then the equation to the line with a slope of "positive" 2 is given by

y = 2x

Then the equation to the line with a slope of "negative" 2 is given by

y = -2x

Refer to the attached image for the graph of the lines with the slope of "positive" 2 and "negative" 2.

f: green line indicates a line with a slope of "positive" 2.

g: blue line indicates a line with a slope of "negative" 2.

What is the initial value in the exponential equation below? y = = 4000(1.05)*

Svet_ta [14]

Answer:

$y = 4000$ (when x = 0)

Step-by-step explanation:

The initial value of the exponential equation is:

$y = 4000\cdot (1.05)^{0}$

$y = 4000\cdot 1$

$y = 4000$

The equation x=ay^2 describes a parabola if the value is a positive which way does the parabola open

aleksandr82 [10.1K]

You can always make up numbers and try to draw it.
Let's say a = 1 for sake of simplicity.

If y=0 then x=0
If y=1 then x=1
If y=-1 then x=1
If y=2 then x=4
If y=-2 then x=4

As you can see, parabola opens to the right. Try drawing it to make sure you believe that.
Keep in mind, parabola only opens to the right if you are using the conventional x-y plane, where x-axis is horizontal and y-axis is vertical.

10 points Help Me Please I will give brainiest

Effectus [21]

Answer:

The slope is 1/2

Step-by-step explanation:

To find the slope you use the formula rise/run

The rise is the second y coordinate minus the first y coordinate

The run is the second x coordinate minus the first y coordinate

Step one:

Take 2 points: I used (2,1) and (4,2)

Step two:

Use the formula

2-1/4-2

The answer is the slope of the line

The slope is 1/2
