The equation that represents the function is y = -x - 1
<h3>How to determine the equation of the function?</h3>The complete question is added as an attachment
From the table of values, we have the following points
(x, y) = (-1,0) and (0,-1)
Calculate the slope (m) using
m = (y2 - y1)/(x2 - x1)
Substitute the known values in the above equation
m = (-1 -0)/(0 + 1)
Evaluate the exponent
m = -1
The equation is then calculated as:
y = mx + c
This gives
y = -x + c
Using the point (0,-1), we have:
0 = 1 + c
Solve for c
c = -1
So, we have
y = -x - 1
Hence, the equation that represents the function is y = -x - 1

Answer:
(B) 18 cm x 8 cm
Step-by-step explanation:
let the length be x,
then the width is x + 2
2( x + 2 + x ) = 52
x + 2 + x = 26
= 24
x = (24*3)/4
x = 18
then the length is 18 cm
and width is (1/3)*18 + 2 = 8
Therefore the dimensions are length:width = 18 cm : 8 cm
