Need math help for this

Burka [1]

Answer:

<h2>In the attachment</h2>

Step-by-step explanation:

The point-slope form of an equation of a line:

$y-y_1=m(x-x_1)$

m - slope

(x₁, y₁) - point

We have the equation:

$y-5=-\dfrac{2}{3}(x+9)\\\\y-5=-\dfrac{2}{3}(x-(-9))$

Therefore we have

the slope m = -2/3

and the point (-9, 5)

A slope

$m=\dfrac{rise}{run}$

rise = -2

run = 3

From the point (-9, 5) ⇒ 2 units down and 3 units to the right.
