Hey there :)
y =
Since this line is parallel to the line to be found, both have the same slope:
Coordinates: ( - 9 , - 2 )
y - ( -2 ) = ( x - ( -9 ) )
y =
Since this line is parallel to the line to be found, both have the same slope:
Coordinates: ( - 9 , - 2 )
y - ( -2 ) =
Answer:
D.
Step-by-step explanation:
The equation given takes the point-slope form which is, . Where,
(a, b) = (x, y) coordinates of a point on the line.
m = slope of the line .
To find which graph has a line equation of , look for the points which will give you something almost exactly as the equation if you substitute their values into
.
Let's consider option D.
We have a given point (1, 2). a = 1, b = 2.
Substitute these into
We have:
As you can see, this looks almost exactly as
.
If you want to be certain that option D is the answer, find m by using the coordinates of any other point on the line and plug into to find m:
In graph D, let's take the points (0, -1)
Divide both sides by -1
3 = m
m = 3.
Therefore, option D is the graph of the line .
Answer: None of the above are correct.
Step-by-step explanation:
Given function:
We know that the value of tan x =0 at x=0.
Also,
Hence, the only option is correct is "None of the above are correct".
