Math Problem Statement

Graph this line using the slope and y-intercept: y=-6x+5

Solution

To graph the line given by the equation y=6x+5y = -6x + 5, we'll use the slope-intercept form y=mx+by = mx + b, where:

  • mm is the slope
  • bb is the y-intercept

In this equation:

  • The slope m=6m = -6 means the line goes down 6 units for every 1 unit it moves to the right.
  • The y-intercept b=5b = 5 means the line crosses the y-axis at (0,5)(0, 5).

Steps to graph the line:

  1. Plot the y-intercept: Start by plotting the point (0,5)(0, 5) on the graph (the y-axis at 5).
  2. Use the slope: From the point (0,5)(0, 5), use the slope m=6m = -6. This means you move down 6 units and right 1 unit to find another point on the line.
    • Start from (0,5)(0, 5) and move to (1,1)(1, -1).
  3. Draw the line: Connect the two points with a straight line.
