Math Problem Statement

Consider the equation y = -3x - 2. Fill in the blanks to complete the table of values.

Solution

We are given the linear equation y=3x2y = -3x - 2, and we need to complete the table of values for different xx-values.

The equation tells us that for any value of xx, we can calculate yy by substituting the value of xx into the equation y=3x2y = -3x - 2.

Let's calculate the values for each xx in the table:

  1. For x=3x = -3: y=3(3)2=92=7y = -3(-3) - 2 = 9 - 2 = 7

  2. For x=0x = 0: y=3(0)2=02=2y = -3(0) - 2 = 0 - 2 = -2

  3. For x=3x = 3: y=3(3)2=92=11y = -3(3) - 2 = -9 - 2 = -11

  4. For x=6x = 6: y=3(6)2=182=20y = -3(6) - 2 = -18 - 2 = -20

Now, the completed table is:

\hline x & -3 & 0 & 3 & 6 \\ \hline y & 7 & -2 & -11 & -20 \\ \hline \end{array}$$ Would you like a more detailed explanation of any step? Here are some related questions to explore: 1. How do you graph the equation $$y = -3x - 2$$? 2. What is the slope and y-intercept of the equation $$y = -3x - 2$$? 3. How would the table change if the equation was $$y = 3x - 2$$? 4. How do we determine if a line is increasing or decreasing from its equation? 5. What happens to the y-values if you increase the x-values in the equation $$y = -3x - 2$$? **Tip:** To quickly find values for linear equations, remember to calculate the slope first and apply it consistently across all x-values.
