9. Linear function f(x) = x is graphed on a grid. The graph of a new line is formed by changing the 5
slope of the original line to and the y-intercept to -8. Which of the following statements are true?
I. The graph of the new line is steeper than the original line.
II. The y-intercept has been translated down.
III. The new line and the driginal line are parallel.
a. I only
b. Il only
c. I and II
d. II and III

step-by-step explanation:

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation

graph of this function as shown below:
