Quizizz Graphing Systems of Equations to Solve

Which equation represents the following graph?

• y = 3x + 2
• y = -2x + 3
• y = 2x + 3
• y = -3x + 2

Find the equation of the line in slope-intercept form. 

• y = - 1/4x - 3
• y = 1/3x + 3
• y = - 1/4x + 2
• y = 1/3x -3

Write the equation in slope-intercept form (solve for y):
2y = 10x + 14

• y = 10x + 12
• y = 10x + 7
• y = 5x + 14
• y = 5x + 7

If a system of linear equations has one solution, what does this mean about the two lines? 

• Parallel lines
• the same line 
• Intersecting lines

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

• Intersecting lines
• Same line
• Parallel lines

Lesly graphed two lines in order to find the solution to a given system of equations.
What is the solution?

• (-3,-8)
• (-8,-3)
• (3,-8)
• (8,3)

Which ordered pair is the solution to this system?

HINT: plug the x number into the x in each equation and plug the y number into the y in each equation and solve to see which one works for BOTH!)
