Place a point at (0,-5) because that is the y-intercept (the -5 on the vertical line)
Since the slope is negative two which can be re-written as -2/1 (rise/run) you go down two and to the right once or up two and to the left once, it doesn't matter which. Another point can be placed at (1,-7) or (-3,-1), it still doesn't matter which.
Then you can draw a line connecting the two points.
I hope this helps :)

Step-by-step explanation:
We have the following information:
Fredburguer , milkshake
and an order of fries
costs
:
(1)
One Fredburguer is equal to a milkshake plus orders of fries:
(2)
Three milshakes is equal to a Fredburguer plus an order of fries:
(3)
And we are asked: If we have a Fredburguer, a milkshake and two orders of fries, how much do we have to pay?
(4)
Well with the first three equations we have a system of equations to solve. Let's begin by isolating from (3):
(5)
Making (2)=(5):
(6)
Isolating :
(7)
Substituting (7) in (2):
(8)
Isolating :
(9)
Substituting (7) and (9) in (1):
(10)
Isolating :
(11) This is the cost of a Milkshake
Substituting (11) in (7):
(12)
(13) This is the cost of an order of frieds
Substituting (11) in (9):
(14)
(15) This is the cost of a Fredburguer
Substituting (11), (13) and (15) in (4):
(16)
Finally:
This is the cost of a Fredburguer, a milkshake and two orders of fries
