hope helps with the first the rest i cant read its not clear.
Answer:
1.8
Step-by-step explanation:
To do this, you need the slope formula
y^2 - y^1 over
x^2 - x^1
x^1 y^2 x^2 x^1
( 5, 11) (-5 -1)
-7 - 11 = -18
-5 -5 = -10 (divide) = 1.8
This problem can be simplified by remembering that since

, we have

. Then we have

.
<span>2<span>(x+4)
</span></span><span>=<span>(2)<span>(x+4<span>)
</span></span></span></span>=<span><span>(2)(x)</span>+<span>(2)<span>(4<span>)
</span></span></span></span>
=<span><span>2x</span>+<span>8
</span></span>
I hope this helps you and have a great day! :)
