Which of the following is a quadrantal angle

Setler [38]

Question:

Which of the following is a quadrantal angle?

a) π/2 b) π/3 c) 2π/3 D) 4π/5

Answer:

$(a)\ \frac{\pi}{2}$

Step-by-step explanation:

Required

Which of a to d is a quadrantal angle

An angle is said to be quadrantal if and only if the angle has its terminal side on the x or y axis.

Such angles (in degrees) are: 90, 180, 270, etc.

So, we have:

$(a)\ \frac{\pi}{2}$

[Convert to degrees]

$\frac{\pi}{2} = \frac{180}{2}$

$\frac{\pi}{2} = 90$

Hence:

$(a)\ \frac{\pi}{2}$ is a quadrantal angle

<em>The other options are not.</em>

Given that slope = -1 and a point (3,-1), write an equation in slope-

stealth61 [152]

Y=Mx+b

Slope/M= -1
X= 3
Y= -1

-1 = -1(3)+b

-1 = -3 + b

Add +3 to -3 and -1 to cancel -3 out to get (b)

-3+3 = 0 cancel it

-1 +3 = 2

So, b = 2

In an equation it will be written as

y= -1x + 2

In standard form it will be

1x + y = 2

But your official answer will be

B= 2
Y= -1x+2
