A1 Lesson 4-1B Solving Systems of Linear Equations

The solution of a system of linear equations is...

• the y-intercept (b)
• the intersection of the two equations on a graph
• the second equations' answers
• the slope (m)

Which of the following are ways to solve systems of equations? 

• Graphing
• Substitution
• Elimination
• All of the above

What is the solution?

• One Solution
• No solution
• Infinitely Many Solutions
• (0, -1.5)

How many solutions will this system have? 

• No solution
• One Solution
• I Don't Know
• Infinitely Many Solutions

• Yes

• No

What is the value of the x-coordinate to the solution to this system of linear equations?

2x + 3y = 15 and -x + 3y = 3

• 3

• -3

• 6

• 4

What is the value of the y-coordinate in this system of linear equations?

6x + 10y = -32 and 6x + 9y = -27

• y = 5

• y = 0

• y = -5

• y = 1

solve by substitution: y=3x+14
y=-4x

• y=3
• y=1
• y= - 2
• y=4

What is the solution to this system of equations?

• (4, -1)
• (-1, 4)
• (-4, 1)
• (-4, -1)

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

• intersecting lines
• parallel lines
• skew lines
• intersecting lines
