Math Problem Statement

Fill in the missing numbers to complete the linear equation that gives the rule for this table.

Solution

To solve this problem, we are looking for the equation of a line in the form:

y=mx+by = mx + b

where:

  • mm is the slope, and
  • bb is the y-intercept.

Step 1: Calculate the slope mm

The slope mm is calculated using the formula:

m=ΔyΔx=y2y1x2x1m = \frac{\Delta y}{\Delta x} = \frac{y_2 - y_1}{x_2 - x_1}

Using two points from the table, for example, (2,184)(2, 184) and (3,317)(3, 317):

m=31718432=1331=133m = \frac{317 - 184}{3 - 2} = \frac{133}{1} = 133

So the slope m=133m = 133.

Step 2: Find the y-intercept bb

Now, we can use the slope and one of the points to find the y-intercept bb. Using the point (2,184)(2, 184), substitute into the equation y=133x+by = 133x + b:

184=133(2)+b184 = 133(2) + b 184=266+b184 = 266 + b b=184266=82b = 184 - 266 = -82

Thus, the y-intercept b=82b = -82.

Final equation

The linear equation that fits the table is:

y=133x82y = 133x - 82

Would you like further details or have any questions? Here are five related questions you might find interesting:

  1. How do you interpret the slope and y-intercept in the context of this problem?
  2. Can you use other points from the table to verify the equation?
  3. How does changing the slope affect the graph of the line?
  4. What happens to the equation if the y-intercept is a positive number?
  5. How can you solve for xx given a specific yy value?

Tip: The slope tells you how much yy increases for each unit increase in xx, while the y-intercept represents the value of yy when x=0x = 0.
