Answer:

2. quadrant 4

3. quadrant 2

4. quadrant 3

Step-by-step explanation:

You can refer to the picture.

2. Since tan\theta less than 0 which means  tan\theta is negative, sin\theta less than 0 which means  sin\theta is negative.

So, the angle lies in quadrant 4 (Cos quadrant)

3. Since tan\theta less than 0 which means  tan\theta is negative, cos\theta less than 0 which means  cos\theta is negative.

So, the angle lies in quadrant 2 (Sin quadrant)

4. Since tan\theta more than 0 which means  tan\theta is positive, sin\theta less than 0 which means  sin\theta is negative.

So, the angle lies in quadrant 3 (tan quadrant)

<h2>Hello!</h2>

The answer is:

The correct option is the first option:  

y=-4x+64

<h2>Why?</h2>

To write the equation of the line in slope-interception  form we need to extract all the information that we need from the graphic.

We must remember that the slope-interception form of the lines is:

y=mx+b

Where,

y, is the function

m, is the slope of the line

x, is the variable

b, is the y-axis intercept

We can find the slope using the following formula:

m=\frac{ChangeInY}{ChangeInX}

Which is for this case:

m=\frac{64}{16}=4

As we can see from the graphic, the line is decresing, so the sign of the slope "m" will be negative, so:

m=-4

We can find the value of "b" seeing where the line intercepts the y-axis.

As we can see it intercept the y-axis at:  y=64

Then, now that we already know the value of "m" and "b", we can write the equation of the line:

y=mx+b=-4x+64\\y=-4x+64

So, the correct option is the first option:

y=-4x+64

Have a nice day!
