Answer:

y = -6x - 5

Step-by-step explanation:

To find the equation using the point-slope equation, we need the slope and the y-intercept of the line

<u>Finding the slope of the line:</u>

We will calculate the slope between these 2 points:  (-1 , 1) and  (0 , -5)

Slope = Rise / Run

Rise of the line = y1 - y2

Rise = 1 - (-5)

Rise = 1 + 5

Rise = 6

Run of the line = x1 - x2

Run = -1 - 0

Run = -1

Slope of the line:

<em>Slope  = Rise / Run</em>

<em>Slope = 6 / -1</em>

<u>Slope = -6 </u>

<u></u>

<u>Finding the y-intercept:</u>

y-intercept of a line is the y-ordinate of the point where the line intersect the y-axis

From the graph, we can see that the line intersects the y-axis at (0 , -5)

y-coordinate of the point = -5

<u>y-intercept = -5</u>

<u></u>

<u>Equation of the line:</u>

This is the general formula of the slope-intercept:

y = mx + b (where m is the slope of the line and b is the y-intercept )

Replacing the variables

y = (-6)x + (-5)

y = -6x - 5

An interger between -5 and -6
ivolga24 [154]

Answer:

None!

Step-by-step explanation:

First off, what is an integer? An integer is a number that is not a fraction or a whole number but it can be negative or positive.

-5 and -6 are both integers and they are both consecutive integers meaning that they are following one another. So they is no integer between -5 and -6.

Answer:

8a^3

Step-by-step explanation:

Given that;

2^x = a, we want an expression for 8^(x + 1)

we have this as;

8^(x + 1) = 8^x * 8^1

8^x = (2^x)(3)

8^x is thus same as 2^3x

So replace 2^x by a

Thus, we have a^3

Multiply this by the 8 we had initially; that will give;

8 * a^3 = 8a^3
