CCSS.7.EE.B.4B

What is the equation in Point-Slope form

of the line that goes through

the point (6,1) and has a slope of -3?

• y - 6 = -3(x - 1)

• y + 6 = -3(x + 1)

• y - 1 = -3(x - 6)

• y + 1 = -3(x + 3)

April wants to prove that she can solve the system of equations below using the substitution method.
3x + y = 8
y = 4x - 6

Which equation shows the first step in solving the system of equations using the substitution method?

• 7x + 2y = 2
• -x +2y = 2
• 3x + (4x-6) = 8
• 3(4x-6) +y = 8

CCSS.HSA.REI.C.6

Select the piece of this equation I should DEFINITELY START solving FIRST: 4(x+5) = 15x + 5

• Distribute the 4 to the x and to the 5
• Divide both sides by 4
• Subtract 5 from both sides

CCSS.8.EE.C.7B

Select the action I need to take next at this point in the solution: 4x +  6x =  8 + 2

• Combine like terms by adding 4x + 6x = 10 x
• Combine like terms by subtracting 2 from both sides
• Divide both sides by 4 and 6
