The graph of a proportional relationship is a straightline that passes through the origin (0,0).
The only graph with that feature is the option c., so that is the answer.
The other graphs ar linear relationships because the are straighlines that to not pass through the origin.
Answer: the option c.
Answer:
Use a graphing calculator and enter y= -2(x-1)-5
Step-by-step explanation:
To get y all alone you would subtract 5 from each side
Answer: the slope of the line is 2/1
Step-by-step explanation:
Find a point on the graph and the go up twice until you see another point on the graph. So go to the right once. So you have found the slope of the line which is 2/1.

Answer:
Let X be the number.
Twice the number would be 2x
The difference between the two, would be subtraction, so you would subtract 4 from 2x
The equation becomes 2x-4 = 16
Now solve for x:
2x-4 = 16
Add 4 to each side:
2x = 20
Divide both sides by 2:
x = 20/2
x = 10
The number is 10.
