This is simple. :)
All you have to do is plug in each of the coordinates.
So, for the first one, you would take the first option (-2,-9). The equation would look like this: -9=3(-2). -2*3 doesn't equal -9, so you move on to the other options, testing them out.

The second question is the same. For example, you take (2,14), plug it into the equation to make it look like this: 14=-5(2)+4
-5*2=-10
-10+4=-6
So the first option is not correct.

I hope this helps

Answer:

Step-by-step explanation:

$\frac{a^{m}}{a^{n}}=a^{m-n}\\\\a^{-m}=\frac{1}{a^{m}}\\\\\\\frac{x^{2}y^{-3}}{x^{5}y^{2}}=x^{(2-5)}*y^{(-3-2)}\\\\ = x^{-3}*y^{-5}\\\\=\frac{1}{x^{3}y^{5}}$

I need help with the last two questions please

For the image 1, the angular values are x=9⁰ and y=23⁰

For the image 2, the angular values are x=9⁰ and y=14⁰

<h3>What is meant by an angle?</h3>

An angle is a figure in Euclidean geometry made up of two rays that share an endpoint and are referred to as the angle's sides and vertex, respectively. Angles created by two rays are located in the plane where the rays are located. The meeting of two planes can also create an angle. Dihedral angles are what they are. A measure of an angle or of a rotation is also referred to as an angle. The ratio of a circular arc's length to radius is known as this quantity. A geometric angle's arc is centered at the vertex and is bound by its sides.

For the first image x and y values are,

As from the given figure,

(4y-2)⁰=90⁰

4y=90+2

y=92/4

y=23⁰

3x-6=21⁰

3x=27

x=9⁰

Therefore, x=9⁰ and y=23⁰

For the second image x and y values are,

2x+27=90/2

2x+27=45

2x=18

x=9⁰

4y-19=y+23

3y=42

y=14⁰

Therefore, x=9⁰ and y=14⁰
