Answer:
-4/3 is the answer :)
Step-by-step explanation:
Draw two lines that never intersects and those are parallel line. A compass and straightedge helps you make the lines straight.
Answer:
y= 1/3x +3
Step-by-step explanation:
slope: 4-1/3-(-6) =3/9=1/3
point slope: y-4=1/3(x-3)
y-4=1/3x -1
y=1/3x +3

Answer:
3a by 4a
Step-by-step explanation:
For dimensions L and W, the area and perimeter are ...
A = LW = 12a^2
P = 2(L+W) = 14a
Using the second equation, we can find L:
L +W = 7a . . . . . divide by 2
L = 7a -W
Substituting into the area formula gives the quadratic ...
(7a -W)(W) = 12a^2
W^2 -7aW +12a^2 = 0 . . . . arrange in standard form
(W -3a)(W -4a) = 0 . . . . . . . factor (find factors of 12 that total 7)
Then we have the two solutions ...
W = 3a, L = 4a
W = 4a, L = 3a
The rectangle dimensions are 3a by 4a.
