Review for Chapter 5 Test

What is the correct slope-intercept form?

• y = mx + b

• y = mb + x

• y = x

• y = -mx + b

Write the equation in slope-intercept form (solve for y):
2y + 4x = 12

• y = 12 - 4x
• y = 6 - 4x
• y = -2x + 6
• y = -2x + 4

Write the equation in solve-intercept form (solve for y):
3y = 2x + 9

• y = 2/3x + 3
• y = 2x + 3
• y = 2x + 6
• y = 3/2x + 6

• x = -11

• x = 0

• x = 1

• x = 23

What is the solution to the system of equations? 
y = 3x - 8
y = 4 - x

• (3,1)
• (1,3)
• (-3,1)
• (3,-1)

How many solutions?

• One Solution
• No solution
• Infinitely Many Solutions

What is the solution to the system?

• (0, 3)
• (1, -1)
• (-3, 1)
• (1, 3)

What is the number of solutions to the system of equations?

• No Solution

• Infinitely Many Solutions

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
