Answer:
Side Q'S' lies on a line with a slope of -1.
The distance from Q' to the origin is twice the distance from Q to the origin.
Step-by-step explanation:
The explanations are as follows
As we can see from the attached figure that the ΔQ'R'S' is dilated i.e transformation is made or change in size
Now
Based on
(x,y) = (2x,2y)
The intercepts are as follows
For S
(-1,1) = (-2,2)
For Q
(-3,3) = (-6,6)
For S
(2,4) = (4,8)
Based on this we can say that the three above options are correct
Linear equation is the equation in which the highest power of the unknown variable is one.
The given equation the constant 2000 represents the base salary or the fixed salary of the salesman.
To find that what does 2000 represent in the given linear equation we need to know about the linear equation.
<h3>What is linear equation?</h3>Linear equation is the equation in which the highest power of the unknown variable is one.
Given information-
Total sales by salesman each month is dollars.
The total money made by the salesman each month by selling goods of dollars given by,
The above equation given in the problem is the linear equation. In this linear equation the salary of salesman depends on his sales.
The constant amount of $2000 is the fixed amount of the salesman.
The variable is the variable on which the salary of the salesman depends. Thus due to this variable the salary of the salesman changes.
Hence in the given equation the constant 2000 represents the base salary or the fixed salary of the salesman.
