Math Problem Statement

Use the slope-intercept form to graph the equation y = (6/5)x - 4.

Solution

The given equation is in slope-intercept form, y=mx+by = mx + b, where:

  • mm is the slope.
  • bb is the y-intercept (the point where the line crosses the y-axis).

For the equation y=65x4y = \frac{6}{5}x - 4:

  • The slope m=65m = \frac{6}{5}.
  • The y-intercept b=4b = -4.

Steps to graph:

  1. Plot the y-intercept: Start by plotting the point (0,4)(0, -4) on the y-axis.
  2. Use the slope: The slope 65\frac{6}{5} means that for every 5 units you move to the right on the x-axis, you move 6 units up on the y-axis.
    • From the point (0,4)(0, -4), move 5 units to the right and 6 units up, arriving at the point (5,2)(5, 2).
  3. Draw the line: Connect these two points with a straight line.
