Question

X-y=0

6x + 5y = -22

The lines intersect at
A. (2.-2)
B. (-2,-2)
C. (2.2)

Answer 1

B

Explanation:

x - y = 0 ( add y to both sides )

x = y → (1)

6x + 5y = - 22 → (2)

substitute x = y into (2)

6y + 5y = - 22

11y = - 22 ( divide both sides by 11 (

y = - 2

since x = y then x = - 2

the lines intersect at (- 2, - 2 )
