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 using the point-plotting method, we'll follow these steps:
-
Rearrange the equation to slope-intercept form (y = mx + b): Now the equation is in the form , where (the slope) and (the y-intercept).
-
Identify the y-intercept: The y-intercept occurs when . So, the point is .
-
Use the slope to find another point: The slope means that for every 1 unit you move to the right (increasing by 1), you move 2 units up (increasing by 2). Starting from the point , move 1 unit to the right to , and then move up 2 units to . So, the next point is .
-
Plot these points on the graph: Plot the points and , and then draw a straight line through them to represent the equation.
