Write the equation in point-slope form of the line that passes through the given point and has the given slope.
(4, -7); m = -1/4

• y + 7 = -1/4(x - 4)
• y - 4 = -1/4(x + 7)
• y + 7 = 4(x - 4)
• y - 7 = -1/4(x - 4)

Amy is on a weight loss show. When the show began, she weighed 231 pounds. During the show, she lost 4 pounds per week. Which equation represents the amount of weight she lost?

• y = 4 - 231x
• y = 231x - 4
• y = 231 - 4x 
• y = 4x + 231

Jenny went to the sale at Kohl's last weekend.  
T-shirts were on sale for $15 each and hoodies were on sale for $20 each.  If she spent $150 total, write an equation to represent this situation.  

• 20x + 15 = y 
• 35x = y 
• 15x + 20y = 150 
• 150 - 20x = 15y
