Parallel lines have the same slope.
So I plug in the -5 and -4
-4 = 1/2(-5) + b
-4 = -2.5 + b
b = -1.5
So I get y = 1/2x - 3/2
<span>If you are given a convex polygon with </span>

<span> sides and </span>

<span> is the sum of the measures of the interior angles then </span>

<span>.
So, </span>

.


The polygon has
11 sides.
Answer:
18x+18
Step-by-step explanation:
I will give you 2 points.
y+1=1/3(x-3)
y+1=1/3x-1
y=1/3x-2
If x=0:
y=0-2
y=-2
(0,-2)
If x=3
y=3*1/3-2
y=1-2
y=-1
(3,-1)
