Graph the system by using technology.

What is the x-coordinate of the solution?

round to the nearest hundreth.


1) y = 6x - 7

y = 2.2x + 3


2) 4x - y = 2

2x + 9y = -12


Graph the system by hand

Which ordered pair is the best estimate of the solution of the system?


3) y = -4/5x

y = 2/3x - 7

Verified Answer :

1)Simplifyingy = 2.2x + 3


 Reorder the terms:
y = 3 + 2.2x


 Solving
y = 3 + 2.2x


 Solving for variable 'y'.

 
Move all terms containing y to the left, all other terms to the right.

Simplifying
y = 3 + 2.2x Hope i helped
