For solving this "by hand," you put the x- and y-values into the equation and check to see if it is true.
A. 2(0) +3(12) = 36 ≠ 24
B. 2(2) +3(9) = 31 ≠ 24
C. 2(3) +3(6) = 24 . . . . . a solution
D. 2(8) +3(0) = 16 ≠ 24

For this case we have that by definition, the equation of a line in the slope-intersection form is given by:
Where:
m: It is the slope of the line
b: It is the cut-off point with the y axis
We have the following points:
Substituting we have:
Thus, the equation is of the form:
We substitute one of the points and find "b":
Finally, the equation is of the form:

Answer:
The length of the plywood's diagonal(to the nearest tenth) is, 3.6 and 1.4
Step-by-step explanation:
let l be the length and w be the width of the rectangle respectively;
Diagonal(D) of a rectangle is given by:
......[1]
As per the given statement we have;
Diagonal(D) = width + 2
and
= 2w
Now, substitute these in [1] we have;
Squaring both the sides we get;
or
or
Simplify:
......[2]
The quadratic equation is in the form of
the solution is given by:
On comparing with [1] we get
a= 1 , b = -1 and c = -1
Then the solution is:
Simplify:
and
Then, the diagonal D = w+2
For
For
therefore, the length of the plywood's diagonal(to the nearest tenth) is, 3.6 and 1.4
