Is the order that I’m putting them in correct? If it is what are the answers to the others? It it’s wrong what is the correct or
der? Please help! Thanks! :)

Answer:
D(x) is a function
D(x) is a direct variation
D(x) is a rule for the set of points (5.10). (6, 12) and (-2,-4)
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
In this problem
D(x) is a direct variation (linear function)
The variable x is the independent variable or input value
The variable D(x) is the dependent variable or output value
<u><em>Verify each statement</em></u>
case 1) D(x) is a function
The statement is true
see the explanation
case 2) x is the dependent variable
The statement is false
The variable x is the independent variable or input value
case 3) D(x) is a direct variation
The statement is true
see the explanation
case 4) D(x) is a rule for the set of points (5.10). (6, 12) and (-2,-4)
The statement is true
Because
For x=5
substitute in the linear equation
---> is ok
For x=6
substitute in the linear equation
---> is ok
For x=-2
substitute in the linear equation
---> is ok
Answer:
Slope:
Y-Intercept:
Step-by-step explanation:
1. To find the slope, we need to have the equation in slope-intercept form, which is . In this case, our equation is already in this form.
is what your slope is. In this case, our
2. To find the y-intercept we look at value that is in
. In this case,
is
. So, our ordered pair is
.
