Find the slope of the line passing through the points of (3,-5) and (-9,-6)

slavikrds [6]

Answer:

m = ---

Step-by-step explanation:

The formula is y2-y1

---------

x2-x1

(x1,y1) (x2,y2)

(3,-5) (-9,-6)

You get the 2 Y's and subtract them

Do the same with the X's

Y's above , X's below

(y2- y1)

⬇

-6-(-5) -1 1

--------- = ---- = ---- = m

-9-(3) -12 12

⬆

(×2- x1)

This equation is backwards, thats why it was harder to understand. (-9,-6) is farther left and below point (3,-5), making it the REAL first point in the equation.

22<br> Solve for x.<br> 3x - 5 = 10<br> x equals.....<br> help

kramer

Answer:

$x = 5$

Step-by-step explanation:

$3x - 5 = 10$

We want to isolate the x.

$3x - 5 = 10\\+5\;\;\;\;\;\;\;\;\; +5$

$3x = 15$

Now, we want the x not to have a coefficient. We want it just to be x =. We will do this via inverse operations. Since 3 x is 3 multiplied by x, we will divide each side by 3.

$\frac{3x}{3} \;=\;\frac{15}{3}$

$x = 5$
