"1. Construct the function $y = 2x - 4$ in the coordinate plane by first filling out the given table!"

This problem involves plotting the linear function $y = 2x - 4$ on a coordinate plane. To do this, you will need to fill out a table with values of $x$ and their corresponding values of $y$, which can be calculated using the equation $y = 2x - 4$.

Here’s how you can fill in the table:

For each value of $x$, substitute it into the equation $y = 2x - 4$ to find $y$. Here are a few sample calculations:

• For $x = -2$: $y = 2(-2) - 4 = -4 - 4 = -8$
• For $x = 0$: $y = 2(0) - 4 = 0 - 4 = -4$
• For $x = 2$: $y = 2(2) - 4 = 4 - 4 = 0$
• For $x = 4$: $y = 2(4) - 4 = 8 - 4 = 4$

This will give you a table of values that you can use to plot the points on the graph.

Would you like me to create the table and the graph for you?

Here are 5 related questions to expand your understanding:

1. How does the slope of a linear function affect its graph?
2. What does the y-intercept represent in the function $y = 2x - 4$?
3. How can you tell if a linear function has a positive or negative slope by looking at the equation?
4. What happens to the graph if you change the slope in the equation?
5. How can you use a table of values to check the accuracy of your graph?

Tip: When plotting linear functions, two points are enough to define the line, but using three or more ensures accuracy!
