Savatey [412]

Answer:

<h3> $\boxed{ \bold{ \sf{ \boxed{ p = 3}}}}$ </h3>

$\boxed{ \bold{ \sf{ \boxed{n = 1}}}}$

Step-by-step explanation:

1. $\sf{7p - p = 18}$

Collect like terms

⇒ $\sf{6p = 18}$

Divide both sides of the equation by 6

⇒ $\sf{ \frac{6p}{6} = \frac{18}{6} }$

Calculate

⇒ $\sf{p = 3}$

2. $\sf{ - 5n - 4n = - 9}$

Collect like terms

⇒ $\sf{ - 9n = - 9}$

Divide both sides of the equation by -9

⇒ $\sf{ \frac{ - 9n}{ - 9} = \frac{ - 9}{ - 9} }$

Calculate

⇒ $\sf{n = 1}$

Hope I helped!

And your Y axis is ( 6, 6 ).

So from -3 to 2, you going up +5, and from 6 to 6, you not moving anywhere, which means 0.

So the slope is 5/0
