Question

Can someone explain how to do this for like 20 points??

Answer 1

x = - 6

y = 4

Explanation:

y = - x/3 + 2

y + 4 = - 4x/3 => y = - 4x/3 - 4

equality

- x/3 + ³⁾2 = - 4x/3 - ³⁾4

- x + 6 = - 4x - 12

-x + 4x = - 6 - 12

3x = - 18

x = - 6

y = - (-6)/3 + 2

y = 6/3 + 2

y = 2 + 2

y = 4

Answer 2

(-6, 4)

Explanation:

y= -1/3x+2

y+4= -4/3x ⇒ y= -4/3x -4

Comparing the 2 equations by eliminating y

• -1/3x+2= -4/3x -4
• 4/3x -1/3x= -4 -2
• x= -6

x- coordinate found, y- coordinate is:

• y= -1/3*(-6)+2= 2+2= 4

So the solution is:

• x= -6, y= 4

or

• point (-6, 4)
