Answer:
Step-by-step explanation:
One of the given points is the y-intercept. That means you can write the equation in slope-intercept form once you have found the slope.
m = slope = (change in y)/(change in x) = (y2 -y1)/(x2 -x1)
= (-3 -(-2))/(0 -(-3)) = -1/3
The slope-intercept form for slope m and intercept b is ...
y = mx +b
For slope -1/3 and intercept -3, the equation is ...
y = -1/3x -3

Given
See attachment for her sketch
Required
Which equation do not represent the perimeter
From the attached sketch:
--- Length
--- Width
Perimeter (P) is calculated as:
This gives:
---- This represents (A)
Open bracket
---- This represents (B)
In algebra:
means
So, the expression becomes
--- This represents (D)
<em>This implies that (C) does not represent the perimeter</em>
