Finding Rate of Change and Slope

2

Find the slope given the equation, two points, graph, or table on the left. Then, drag the box into the category that describes the slope. Each answer will be used once.

  • Through the points (18,-5) and (18,20)
  • y=3x-1
  • Positive
  • Negative
  • Zero
  • Undefined
1

Find the constant rate of change and interpret its meaning.

2

Find the slope given the set of ordered pairs. Then, drag the slope that matches.

  • m= 14
  • m= -2/5
  • m= 0
  • m= Undefined
  • m= -2/3
  • m= -4
  • m= 26/3
  • m= 6/15
  • (-15,9) (0,3)
  • (1,-19) (-2,-7)
  • (18,-5) (18,20)
  • (3,-20) (5,8)

You will use this problem to answer two questions.
Movie tickets cost $12 for adults and $6 for children. A family has $48 to spend on movie tickets. If x represents the number of adult tickets and y represents the number of childrens tickets, this situation can be modeled by the equation 12x+6y=48. What is the x-intercept of the equation?
