What is the slope of the line that passes through (-4, 5) and (2, -3)?

vagabundo [1.1K]

Slope <em>m</em> has a form of,

$m=\dfrac{\Delta{y}}{\Delta{x}}=\dfrac{y_2-y_1}{x_2-x_1}$

We have points <em>A</em> and <em>B</em>,

$A(x_1,y_1),B(x_2,y_2)\longrightarrow A(-4,5),B(2,-3)$

Now insert the values in the slope formula,

$m=\dfrac{-3-5}{2-(-4)}=\dfrac{-8}{6}=\boxed{-\dfrac{4}{3}}$

The answer is A.

Hope this helps.

What are the values of a 1 and r of the geometric series? 1 + 3 + 9 + 27 + 81 a 1 = 1 and r = one-third a 1 = one-third and r =

Dahasolnce [82]

Answer:

Step-by-step explanation:

$1+3+9+27+81\\\\a_1=1,\ a_2=3,\ a_3=9,\ a_4=27,\ a_5=81\\\\r=\dfrac{a_{n+1}}{a_n}\Rightarrow r=\dfrac{a_2}{a_1}=\dfrac{a_3}{a_2}=\dfrac{a_4}{a_3}=\dfrac{a_5}{a_4}\\\\r=\dfrac{3}{1}=\dfrac{9}{3}=\dfrac{27}{9}=\dfrac{81}{27}=3$
