Lesson 12 Graphing equations

Lesson 12 Solving Systems of Equations with Graphing

Ms. Gurley and Mr Tison

You must watch BOTH videos before you answer the questions in this quizziz lesson. This is a retake of your Lesson 12 quiz from last week so only your FIRST attempt at the questions will be counted.

GOOD LUCK!!!

Multiple Choice

How can you tell if a point is a solution to a system?

• It makes the first equation true.

• The (x,y) coordinates satisfy both equations

• It makes logical sense

• It makes neither equation negative

Multiple Choice

The solution is:

• (4, 3)

• (3, 4)

• (-4, 3)

• No solution

Multiple Choice

If a system of linear equations has infinitely many solutions, what does this mean about the two lines?

• Intersecting lines

• Same line

• Parallel lines

Multiple Choice

How many solutions will this system have?

• One

• Two

• No Solution

• Infinitely Many Solutions

Multiple Choice

Parallel Lines never intersect because...

• they have the same slopes.

• they have the same y-intercept.

• they have different slopes.

• they have different y-intercepts.

Multiple Choice

How many solutions will this system have?

• No Solution

• Infinitely Many Solutions

• No Clue

• One solution

Multiple Choice

^{What is the solution?}

• 1

• -2

• (1, 2)

• (1, -1)

Multiple Choice

If a system of equations has no solution, what does the graph look like?

• intersecting lines

• parallel lines

• skew lines

• intersecting lines

Multiple Choice

Which is the graph of y= -x + 2?

• A

• B

• C

• D

Multiple Choice

The solution to the system is

• (-2, -8)

• (-8, -2)

• (2, -8)

• No solution
