Which is the graph of f(x) = (4)x?
1 answer:
Answer:
f(x)=4x
Step-by-step explanation:
In order to make the graph of f(x)= 4x we will find out few coordinates first and then plot them on the graph. In order to find the coordinates we will find the values of f(x) for random values of x .
Let us see:
x=1 ; f(x) = 4(1) = 4
x=2 ; f(x) = 4(2)=8
x=0 ; f(x) = 4(0)=0
x=-1 ; f(x)= 4(-1) = -4
x=-2 ; f(x)=4(-2)= -8
Hence our coordinates are
(-2,-8) ; (-1,-4) ; (0,0) ; (1,4) ; (2,8)
Now we plot those coordinates on x - y plane and join them to make our line. Please see the graph in the attachment.

Answer:
3/4
Step-by-step explanation:
First of all, we need to calculate the slope of the line shown. This can be computed as:
where
is the increment along the y-direction
is the increment along the x-direction
We can choose the following two points to calculate the slope of the line shown:
(-3,2) and (0,-2)
And so, the slope of the line shown is
Two lines are said to be perpendicular if the slope of the first line is the negative reciprocal of the slope of the second line:
Using , we find that a line perpendicular to the line shown should have a slope of
