x + y = 15------(1)

x/y = 2------(2)

y = 15 - x

put this value in eq 2

x/(15-x) = 2

x = 2 (15 - x)

x = 30 - 2x

2x + x = 30

3x = 30

x = 10

y= 15 - x

y = 15 - 10

y = 5

Solution:

<u>Given:</u>

  • x + y = 15
  • x/y = 2

<u>Let’s simplify the second equation to find out the value of x.</u>

  • x/y = 2
  • x = 2y

<u>Now, let’s substitute the value of x into the first equation.</u>

  • x + y = 15
  • 2y + y = 15
  • 3y = 15
  • y = 5

<u>Now, let’s substitute the value of y into the simplified second equation.</u>

  • x = 2y
  • x = 2(5)
  • x = 10

Hence, the value of x and y are 5 and 10 respectively.

Answer:

m=-2

Step-by-step explanation:

The two given points are: (-3, -2) and (-2, -4)

The equation for slope is m=\frac{y_2-y_1}{x_2-x_1}

m=\frac{(-4)-(-2)}{(-2)-(-3)}

m=-2/1

m=-2
