Question

do the line of equation 2x + Y + 4 is equals to zero and X + 2y - 5 = 20 intersect justify your answer​

Answer 1

2x + y + 4 is equal to 0

2x + y is equal to 0-4

3y is equal to -4

y is equal to -4/3

Answer 2

From question,

Equations:

2x+y+4=0

x+2y-25=0

a1/a2=2/1

b1/b2=1/2

As a1/a2 is not equal to b1/b2, these lines intersect.
