given f(x) and g(x) = f(k⋅x), use the graph to determine the value of k.
a. 5
b. 1/5
c. -1/5
d. −5

Step-by-step explanation:

B is the answer

step-by-step explanation:

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
