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 forx y
3. Calculate points:
* Forx = 0 y = 2(0) - 4 = -4 (0, -4)
* Forx = 2 y = 2(2) - 4 = 0 (2, 0)
* Forx = -1 y = 2(-1) - 4 = -6 (-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)
