Answer:
The relationship is proportional.
The relationship is linear.
The equation of the line is y = –3x.
Step-by-step explanation:
The line in the question passes through origin and (4,-12).
The rate of change of the line is
The rate of change of the line or slope of the line is -3
Equation of the line is given by
This means that the relationship is linear.
If we take any value of x then there will be only one value of y this means that the relationship is proportional.
So the following statements are true
The relationship is proportional.
The relationship is linear.
The equation of the line is y = –3x.
The equation is saying . We can use algebra to subtract 3 from both sides to create
.
Therefore, the value t is greater or equal to 18.
