Solve the system by graphing

{y = 7 - x

{x + 3y = 11

Classify the system without graphing

{2x + y = 3

{y = - 2x - 1

A) Independent System

B) Dependent System

C) Inconsistent System

Classify the system without graphing

{x + 3y = 9

{-2x - 6y = - 18

A) Dependent System

B) Independent System

C) Inconsistent System

Solve the system by graphing

{y = 7 - x the slope is - 1 and the y intercept is 7

{x + 3y = 11 3y = - x+11 y = 1/3 x + 11/3 the slope is 1/3 and the y intercept is 11/3

The solution is x=5, y=2 you will need to graph

Classify the system without graphing

{2x + y = 3 y = - 2x+3

{y = - 2x - 1

These lines are parallel same slope different y intercept

C) Inconsistent System

Classify the system without graphing

{x + 3y = 9

{-2x - 6y = - 18 divide by - 2

x+3y = 9

same line

A) Dependent System
