Hello,

Answer:

The last graph (2;3)

Step-by-step explanation:

2x + 3y = 12

2x – 3y = 0

2x + 3y = 12

2x = 3y

3y + 3y = 12 ⇔ 6y = 12 ⇔ y = 12/6 = 2

2x + 3 × 2 = 12 ⇔ 2x + 6 = 12 ⇔ 2x = 6 ⇔ x = 6/2 = 3

Pythagorean Theorem: A² + B² = C²

You would use it to find a missing side or missing hypotenuse of a right triangle by pluggin in all of the known values of the triangle into the equation and then solving it.

Step-by-step explanation:

C² is the hypotenuse of the triangle (the longest side, and the side that is opposite the right angle).

A² and B² are the remaining two sides.

A proportional relationship is also known as a direct variation

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $y/x=k$ or $y=kx$

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

In a proportional relationship

If the variable x increases -------> the variable y increases

If the variable x decreases -------> the variable y decreases
