Solving Systems and Linear Functions Review

Solve the system of equations.
y = 4x+1
3x + 2y = 13

• (1, 5)

• (5, 1)

• (1/4, 2)

• No Solution

Determine if (4, 1) is a solution for the system of equations.
y = -x + 5
y = 2x - 7

• yes

• no

Solve the linear system:

y = 2/3x - 2

y = -x + 3

• (0,3)

• (0,-3)

• (3,0)

• (-3,0)

Solve the linear system:

3x + 2y = 16

7x + y = 19

• (-2,5)

• (-2,-5)

• (2,5)

What is the Solution to this system?

• (2,-2)

• (0, 0)

• Infinite Solutions

• No Solution

If a system of equations has infinite solutions, what does the graph look like? 

• lines intersect

• parallel lines

• lines coincide

Solve the linear system:

-x + y = -13

-8x - 4y = -8 

• (5, 8)

• (5, -8)

• (-5, -18)

• (-5, 8)

The coordinate point that satisfies BOTH equations in a linear system is called the _____________________.

• system of equations

• function

• graph

• solution 

Is (-2, -6) a solution for this system of equations?

• Yes

• No

• Maybe

Your family goes to a restaurant for dinner. There are 6 people in your family. Some order the chicken dinner for $14.80, and some order steak for $17. If the total bill was $91, which system best represents the situation? 

• x + y = 6
  14.80x + 17y = 91

• x + y = 91
  14.80x + 17y = 6

• x + y = 6
  14.80y + 17x = 91

• x + y = 91
  14.80x+ 17y = 6
