Math Problem Statement

Create a linear model for the data in the table. x: [2, 6, 9, 10, 11, 13, 17], y: [5, 11, 14, 16, 18, 21, 27]

Solution

The problem asks to create a linear model for the data given in the table. We can write a linear equation in the form:

y=mx+by = mx + b

Where:

  • mm is the slope of the line.
  • bb is the y-intercept.

We can calculate the slope mm using the formula:

m=y2y1x2x1m = \frac{y_2 - y_1}{x_2 - x_1}

Let's take two points from the table. For instance, the points (2,5)(2, 5) and (6,11)(6, 11):

m=11562=64=1.5m = \frac{11 - 5}{6 - 2} = \frac{6}{4} = 1.5

So, the slope m=1.5m = 1.5.

Next, we use the slope-intercept form to find the y-intercept bb. Using the point (2,5)(2, 5):

5=1.5(2)+b5 = 1.5(2) + b 5=3+b5 = 3 + b b=53=2b = 5 - 3 = 2

Thus, the linear model is:

y=1.5x+2y = 1.5x + 2

Would you like more details or have any questions? Here are some related questions you might find useful:

  1. What is the method to calculate the slope if only two points are provided?
  2. How do you verify if a set of points follows a linear model?
  3. Can you create a different linear model using other pairs of points from the table?
  4. What is the significance of the slope in a linear model?
  5. How does the y-intercept affect the graph of the equation?

Tip: When calculating a linear model from data, always use more points to ensure consistency in your slope and intercept.
