Question

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

Answer 1

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
