Video Solution

Solution Steps

00:00 Determine if the rate of change is uniform?
00:07 It appears that the change in X values is always equal
00:12 It appears that the change in Y values is always equal
00:15 Therefore, the rate of change is uniform
00:18 And this is the solution to the question

Step-by-Step Solution

To solve this problem, we'll follow these steps:

  • Step 1: Calculate the rate of change between each pair of consecutive points.
  • Step 2: Compare the computed rates to determine if they are equal.
  • Step 3: Conclude whether the rate of change is uniform or not.

Now, let's work through each step:
Step 1: Calculate the rate of change between each pair of consecutive points:
- Between (2,3)(2, 3) and (4,6)(4, 6):
Slope=6342=32=1.5 \text{Slope} = \frac{6 - 3}{4 - 2} = \frac{3}{2} = 1.5
- Between (4,6)(4, 6) and (6,9)(6, 9):
Slope=9664=32=1.5 \text{Slope} = \frac{9 - 6}{6 - 4} = \frac{3}{2} = 1.5
- Between (6,9)(6, 9) and (8,12)(8, 12):
Slope=12986=32=1.5 \text{Slope} = \frac{12 - 9}{8 - 6} = \frac{3}{2} = 1.5

Step 2: Compare the computed rates:
- In all cases, the rate of change is 1.51.5.

Step 3: Conclude that the rate of change is uniform across the expressed intervals.

Therefore, the rate of change for the given points is uniform.

Answer

Uniform
