The slope, m, of a linear equation can be found using the formula <img src="https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7By_2%20-%

Answer:

Answer c: $m(x2 - x1) + y1 = y2$

Step-by-step explanation:

Hi there!

Let´s start writting the formula

$m = \frac{y2 -y1}{x2-x1}$

If we multiplicate both sides by (x₂ - x₁):

$m(x2 - x1) = y2 - y1$

Then if we add y₁ to both sides of the equation:

$m(x2 - x1) + y1 = y2$

Then, the right answer is the answer c)

Have a nice day!

For which value(s) of x will the rational expression below equal zero? Check all that apply.

Ivahew [28]

Answer: D.-6 and F.3

Step-by-step explanation:

The given rational number : $\dfrac{(x-3)(x+6)}{(x+7)}$

To find : The value of x , where the rational expression becomes equal zero.

Let's check all the options :

A. 7

At x= 7 , $\dfrac{(7-3)(7+6)}{(7+7)}=\dfrac{26}{7}\neq0$

B. -7

At x= 7 , $\dfrac{(-7-3)(-7+6)}{(-7+7)}=\dfrac{10}{0}=\infty\neq0$

C. 6

At x= 6 , $\dfrac{(6-3)(6+6)}{(6+7)}=\dfrac{36}{13}\neq0$

D. -6

At x= -6 , $\dfrac{(-6-3)(-6+6)}{(-6+7)}=\dfrac{0}{1}=0$

E. -3

At x= -3 , $\dfrac{(-3-3)(-3+6)}{(-3+7)}=\dfrac{-9}{2}\neq0$

F. 3

At x= 3 , $\dfrac{(3-3)(3+6)}{(3+7)}=0$

Thus, at x= -6 and 3 , the rational expression equals to zero .

So , the correct options are : D.-6 and F.3
