Determining the X and Y Intercepts
To find the x and y intercepts of the equation x = 4y + 8, we need to follow these steps:
Finding the Y-Intercept
The y-intercept occurs when x = 0. We substitute x = 0 into the equation:
0 = 4y + 8
Now, rearranging the equation gives us:
4y = -8
y = -2
Thus, the y-intercept is (0, -2).
Finding the X-Intercept
The x-intercept occurs when y = 0. We substitute y = 0 into the equation:
x = 4(0) + 8
This simplifies to:
x = 8
Thus, the x-intercept is (8, 0).
Plotting the Intercepts
Now that we have both intercepts:
- Y-Intercept: (0, -2)
- X-Intercept: (8, 0)
To graph these intercepts on a coordinate plane:
- Plot the point (0, -2) on the y-axis.
- Plot the point (8, 0) on the x-axis.
- Draw a line connecting these two points to visualize the equation x = 4y + 8.
Conclusion
By finding the x and y intercepts, we have made it easier to graph the equation x = 4y + 8. These intercepts provide critical points that help define the behavior of the graph, and plotting them gives us a clear visual representation of the relationship between x and y.
