Which equation is a point slope form equation for line AB ?

Jobisdone [24]

For this case we have that by definition, the equation of a line of the point-slope form is given by:

$y-y_ {0} = m (x-x_ {0})$

Where:

m: It's the slope

$(x_ {0}, y_ {0}):$ It is a point through which the line passes

To find the slope, we need two points through which the line passes, observing the image we have:

$(x_ {1}, y_ {1}): (1,6)\\(x_ {2}, y_ {2}): (5, -2)\\m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}} = \frac {-2-6} {5-1} = \frac {-8} {4} = -2$

Thus, the equation is of the form:

$y-y_ {0} = - 2 (x-x_ {0})$

We choose a point:

$(x_{0}, y_ {0}) :( 5, -2)$

Finally, the equation is:

$y - (- 2) = - 2 (x-5)\\y + 2 = -2 (x-5)$

Answer:

$y + 2 = -2 (x-5)$

What are the steps for this problem? -10-8n=n-(8n+8)

Elden [556K]

Answer:

$n = - 2$

Step-by-step explanation:

$- 10 - 8n = n - (8n + 8)$

First, you should distribute the -1 on the right.

$- 10 - 8n = n - 8n - 8$

Next, add 8n to both sides. This should cancel out the 8n.

$- 10 = n - 8$

Now, add 8 to both sides. This will get n by itself.

$- 2 = n$

Your answer is n = -2.
