That would be Quadrant 1, which is the quadrant in the top right corner.

Sin corresponds to the y-value, so sin would be positive at Quadrants 1 and 2.

Tan, which is y/x (sin/cos), is positive at Quadrants 1 and 3.

So at quadrant 1 is where both sin and tan are positive.

Determine the equation of the line shown in the graph: y = −1 y = 0 x = −1 x = 0

BaLLatris [955]

Answer:

Option C.

Step-by-step explanation:

If a vertical line intersects the x-axis at point (c,0), then the equation of line is x=c.

From the given figure it is clear that it is a vertical line and it intersects the x-axis at (-1,0). There are infinite values of y at x=-1.

So, the equation of given line is

$x=-1$

Therefore, the correct option is C.
