Question 6: Graph a relationship in which the value of y is 4 less than twice the value of x.

Solution:
1. Express the relationship in the form of an equation:
- y = 2x - 4

2. Identify key points to graph this linear equation:
- Choose some values for x and solve for corresponding y values.

3. Calculate points:
* For x = 0, y = 2(0) - 4 = -4. Point: (0, -4).
* For x = 2, y = 2(2) - 4 = 0. Point: (2, 0).
* For x = -1, y = 2(-1) - 4 = -6. Point: (-1, -6).

4. Plot these points on a graph and draw a line through them to represent the equation.

5. The graph is a straight line with a slope of 2, cutting through these points:
* Points to plot:
- (0, -4)
- (2, 0)
- (-1, -6)

6. The graph is accurate representation of the linear relationship y = 2x - 4.
