Question

apply equaton (x+y)÷2

a) -10,-6
b)-4,2
c)8,-20​

Answer 1

Answer:

Hope this answer helps you ??

Step-by-step explanation:

The straight line in the first case passes through (4,0) and (0,4).  

Hence its equation (by application of intercept form) will be x+y=4...(i)

The straight line in the second case passes through (0,−6) and (−8,−8).  

Hence, its equation is given by  

x+8

y+8

​  

=  

x

y+6

​  

 

⇒8x=6x+8y+48  

⇒2x=8y+48

⇒x−4y=24....(ii)  

Solving equation (i) and (ii) gives us the intersection point as x=8 and y=−4.
