Need help!! What is the slope of the line through (2,-2) and (9,3)?

In-s [12.5K]

Finding the slope using two points:

The formula for slope is

$\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

In this case...

$y_{2} =3\\y_{1} =-2\\x_{2} =9\\x_{1} =2$

^^^Plug these numbers into the formula for slope...

$\frac{3 - (-2) }{9 - 2}$

A) $\frac{5}{7}$

^^^This is your slope

Hope this helped!

the base must be raised

for example

$log_{10}$ 55 = n ( the base is 10 ), then

55 = $10^{n}$

Answer:

3 x (3 x - 5) (3 x + 5)

Step-by-step explanation:

Factor the following:

27 x^3 - 75 x

Factor 3 x out of 27 x^3 - 75 x:

3 x (9 x^2 - 25)

9 x^2 - 25 = (3 x)^2 - 5^2:

3 x (3 x)^2 - 5^2

Factor the difference of two squares. (3 x)^2 - 5^2 = (3 x - 5) (3 x + 5):

Answer: 3 x (3 x - 5) (3 x + 5)
