How many solutions for the system of equations 4x + 6y = 12,6x +9y = 18
Mariana [72]

Answer:

infinite number of solutions

Step-by-step explanation:

Given the 2 equations

4x + 6y = 12 → (1)

6x + 9y = 18 → (2)

Equation (2) is a multiple of (1)

Each term has been multiplied by 1.5

Thus the 2 equations are basically the same equation.

This indicates there are infinite solutions to the system

What is the slope of the line that passes through the points (-8,-1) and (-8,11)?
lubasha [3.4K]

Answer: \text{Slope}=\Large\boxed{Unde fined}

Step-by-step explanation:

<u>Given information</u>

(x_1,~y_1)=(-8,~-1)

(x_2,~y_2)=(-8,~11)

<u>Given the formula for the slope</u>

\text{Slope}=\dfrac{\Delta y}{\Delta x}=\dfrac{y_2-y_1}{x_2-x_1}

<u>Substitute values into the formula</u>

\text{Slope}=\dfrac{(11)-(-1)}{(-8)-(-8)}

<u>Simplify the numerator and the denominator</u>

\text{Slope}=\dfrac{11+1}{-8+8}

\text{Slope}=\dfrac{12}{0}

<u />

<u>Simplify the fraction</u>

\text{Since any number divided by 0 is impossible to find, therefore: }

\text{Slope}=\Large\boxed{Unde fined}

Hope this helps!! :)
