Answer:

x = -6

Step-by-step explanation:

13x = 3(x - 20) {Use distributive method:a(b+c)=(a*b) + (a*c)

13x = 3*x - 3*20

13x = 3x - 60 {Subtract '3x' from both sides}

13x -3x = -60

10x = -60 {Divide both sides by 10}

x= -60/10

x = -6

Aline crosses the coordinates (-4,4) and (2.-5). What is the slope<br> of the line?

lisabon 2012 [21]

Answer:

Step-by-step explanation:

Use the slope formula:

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

where m = slope

Given the coordinates

(-4, 4) ---> this means x1 = -4 , y1 = 4

(2, -5) ---> this means x2 = 2 , y2 = -5

Substitute these values into the slope formula:

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

$m = \frac{-5 -4}{2 - (-4)} = \frac{-9}{2+4} = \frac{-9}{6} = \frac{-3}{2}$
