The answer is the third one.
Answer:
<h2>y = -x - 1</h2>
Step-by-step explanation:
From the graph we have:
y-intercept = -1
x-intercept = -1
The slope-intercept form of an equation of a line:
<em>y = mx + b</em>
m - slope
b - y-intercept
Therefore we have: <em>y = mx - 1</em>
Put the coordinates of the x-intercept to the equation:
(-1, 0) → x = -1 and y = 0:
0 = -1m - 1 <em>add m to both sides</em>
0 + m = -m + m - 1
m = -1
Finally we have the equation:
<em>y = -1x - 1</em>

Answer:
The perimeter is 14 units
<em></em>
Step-by-step explanation:
Given




Required
Determine the perimeter
To do this, we simply calculate the distance between the sides of the rectangle i.e. AB, BC, CD and DA.
Distance (d) is calculated using:

For AB
