Answer 2

1. To plot the functions y = x and y = -2x - 6, we can create a graph with the x-axis representing the values of x and the y-axis representing the values of y.

For y = x:

• Pick a few values for x, such as -2, -1, 0, 1, and 2.
• Substitute each value of x into the equation to calculate the corresponding values of y.
• Plot the points (-2, -2), (-1, -1), (0, 0), (1, 1), and (2, 2) on the graph.

For y = -2x - 6:

• Again, choose a few values for x, such as -2, -1, 0, 1, and 2.
• Substitute each value of x into the equation to find the corresponding values of y.
• Plot the points (-2, 2), (-1, 4), (0, 6), (1, 8), and (2, 10) on the graph.

Connect the points for each equation with a straight line. The resulting graph should show two lines intersecting each other.

2. To graph the functions y = -x and y = 1/2x + 3, follow a similar process:

For y = -x:

• Select values for x, such as -2, -1, 0, 1, and 2.
• Substitute each value of x into the equation to calculate the corresponding values of y.
• Plot the points (-2, 2), (-1, 1), (0, 0), (1, -1), and (2, -2) on the graph.

For y = 1/2x + 3:

• Once again, choose values for x, such as -2, -1, 0, 1, and 2.
• Substitute each value of x into the equation to find the corresponding values of y.
• Plot the points (-2, 2), (-1, 2.5), (0, 3), (1, 3.5), and (2, 4) on the graph.

Connect the points for each equation with straight lines. The resulting graph should display two lines intersecting each other.

3. To graph the functions y = 2x + 4 and y = -2x:

For y = 2x + 4:

• Select values for x, such as -2, -1, 0, 1, and 2.
• Substitute each value of x into the equation to calculate the corresponding values of y.
• Plot the points (-2, 0), (-1, 2), (0, 4), (1, 6), and (2, 8) on the graph.

For y = -2x:

• Choose values for x, such as -2, -1, 0, 1, and 2.
• Substitute each value of x into the equation to find the corresponding values of y.
• Plot the points (-2, 4), (-1, 2), (0, 0), (1, -2), and (2, -4) on the graph.

Connect the points for each equation with straight lines. The resulting graph should depict two intersecting lines.
