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, , where:
- is the slope.
- is the y-intercept (the point where the line crosses the y-axis).
For the equation :
- The slope .
- The y-intercept .
Steps to graph:
- Plot the y-intercept: Start by plotting the point on the y-axis.
- Use the slope: The slope 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 , move 5 units to the right and 6 units up, arriving at the point .
- Draw the line: Connect these two points with a straight line.
