Find the slope of the line that contains these points (-2,5) (-4,11)

nevsk [136]

The first thing you have to do is:

subtract: 11-5

Then subtract: -4-(-2)

then you put it as a fraction: 6/-2 or -3

That -3 would be considered the slope.

So now you have: y=-3x+ b

So what you have to do is plug in one of the points into the equation to find out what b is.

For example: 11 = -3(-4) + b
11=12 + b
-12 -12
b = -1
So the answer is: y = -3x -1

Plz help been stuck on this for awhile

Kazeer [188]

Answer:

<em>d</em> = $\sqrt{74}$ or 8.60

Step-by-step explanation:

(5, 8) (-2, 3)

Let 5 = $x_{1}$

8 = $y_{1}$

-2 = $x_{2}$

3 = $y_{2}$

Plug in the values into the equation to get the distance:

<em>d = </em> $\sqrt{(x_{2}-x_{1})^{2} + (y_{2}-y_{1})^{2} }$ <em />

<em>d </em>= $\sqrt{(-2-5)^{2} + (3-8)^{2} }$

<em>d = </em> $\sqrt{(-7)^{2} + (5)^{2} }$

<em>d</em> = $\sqrt{49 + 25}$

<em>d = </em> $\sqrt{74}$ or 8.60
