Math Problem Statement

Graph the linear equation using the​ point-plotting method. negative 2 x plus y equals 5 Question content area bottom left Part 1 Use the graphing tool to graph the linear equation.

Solution

To graph the linear equation 2x+y=5-2x + y = 5 using the point-plotting method, we'll follow these steps:

  1. Rearrange the equation to slope-intercept form (y = mx + b): 2x+y=5y=2x+5-2x + y = 5 \quad \Rightarrow \quad y = 2x + 5 Now the equation is in the form y=mx+by = mx + b, where m=2m = 2 (the slope) and b=5b = 5 (the y-intercept).

  2. Identify the y-intercept: The y-intercept occurs when x=0x = 0. So, the point is (0,5)(0, 5).

  3. Use the slope to find another point: The slope m=2m = 2 means that for every 1 unit you move to the right (increasing xx by 1), you move 2 units up (increasing yy by 2). Starting from the point (0,5)(0, 5), move 1 unit to the right to x=1x = 1, and then move up 2 units to y=7y = 7. So, the next point is (1,7)(1, 7).

  4. Plot these points on the graph: Plot the points (0,5)(0, 5) and (1,7)(1, 7), and then draw a straight line through them to represent the equation.
