Sample Answer from Big Ideas Math Chapter 4

Let’s consider an example problem from Big Ideas Math Chapter 4 and provide the corresponding answer:

Example Problem: Graphing Linear Equation Graph the equation y = 2x + 3.

Answer: To graph the linear equation y = 2x + 3, start by plotting the y-intercept at (0, 3). Then, use the slope (rise over run) to find additional points. For example, if you move up 2 units and right 1 unit from the y-intercept, you get the point (1, 5). Connect the points to form a straight line, which represents the graph of the equation y = 2x + 3.
