the coordinates of the point where the two lines interscet.
​

Answer 1

Answer:

1) 2x+3y=16

expressing x in terms of y

2x=16-3y

x= 16-3y

--------

2

Let y be 0

x= 16-3(0)

-----------

2

x= 16

----

2

x= 8

Let y be 2

x= 16-3(2)

------------

2

x= 16 - 6

--------

2

x=. 10

---

2

x= 5

Let y be 4

x= 16-3(4)

-----------

2

x= 16-12

---------

2

x=. 4

----

2

x= 2

x 8 5 2

y 0 2 4
