Write the following equation in
Slope-Intercept form:
2x - 4y = 16

_{HINT:
Slope-Intercept form: y = mx + b}

• y = ½x + 4
• y = ½x - 4
• y = -½x - 4
• y = -½x + 4

Which of these shows y = -2x + 5
in Standard Form? 

_{HINT:
 Standard Form: Ax+By=C}

• y - 1 = 2(x+2)
• 2x - y = -5
• y = ½x - 5
• 2x + y = 5

Write the equation of a line in Point-Slope Form with a slope of -5 that passes through the point (3, -1).
_{HINT:
Point-Slope Form:} y - y₁ = m(x - x₁)

• 3x - y = -5 
• y = -5x + 3
• y + 1 = -5 (x - 3)
• 3 + y = -5x

You plan to go snowboarding. The resort charges $15 an hour in addition to $25 to rent a board.
Write an equation that represents the cost to go snowboarding for the day.
_{HINT:
Use "x" to represent hours and "y" to represent the total cost.}

• y=15x-25
• 15x+25y=100
• 25x+y=15
• y=15x+25

The marching band is selling hats for $7 and t-shirts for $15. The band's fundraising goal is $600. Write the equation that represents the marching band’s fundraising goal.
_{HINT: 
Use "h" to represent the number of hats. Use "s" to represent the number of t-shirts.}

• h+15s=600
• 7h+15s=600
• 22(h+s)=600
• 7s+7h=600
