Select the correct graph for each inequality. y > ½x + 2

• A

• B

• C

• D

Write an equation in point slope form of equation of line

point (7,10) and has a slope of -2?

• y-10 = -2(x+7)

• y-10 = -2(x-7)

• y+10 = -2(x+10)

• y -10 = -2x+2

Which equation represents the line shown in the graph?

• y = 2x + 5

• y = -2x + 5

• y = 2x - 5

• y = -2x - 5

Find the y-intercept for the equation
3x - 5y = 15

• -3

• 3

• -15

• 15

What is the correct first step to solve this system of equations?

2x - y = 4

y = x - 2

• The variable is already isolated, so we've already solved the system.

• The variable is already isolated for y, so we substitute it in the first equation and solve for x

  2x - (x - 2) = 4

• Free sha vaca doo

• The variable is already isolated for y, so we substitute it in the second equation and solve for x

  y = 2(x - y) = 4

• Infinitely Many Solutions

• No Solution

• One Solution

• Two Solutions

Find the x and y intercepts
3x + 6y = 18

• x intercept is 6
  y intercept is 3

• x intercept is 3
  y intercept is 6

• x intercept is 6
  y intercept is -3

• x intercept is -6
  y intercept is 3

What are the x-intercepts of the graph?

• x= 0 and x= -3

• x= 0 and x= 3

• y= 0

• x= 1

Solve by factoring:  2x²+ 7x + 6 = 0

• x= 3/2 and x = 2
• x = -3/2 and x = -2
• x = 6 and x = 7
• x = -6 and x = -7
