To graph the equation \(9 - x = 32y\) in slope-intercept form, we first need to convert it into the appropriate format \(y = mx + b\), where \(m\) is the slope and \(b\) is the y-intercept.
Starting with the given equation: \[ 9 - x = 32y \]
Let's isolate \(y\):
-
Rearrange the equation to get \(32y\) alone on one side: \[ 32y = 9 - x \]
-
Divide every term by 32 to solve for \(y\): \[ y = \frac{9}{32} - \frac{1}{32}x \]
Now we can rewrite this as: \[ y = -\frac{1}{32}x + \frac{9}{32} \]
From this form, we can see that the slope \(m\) is \(-\frac{1}{32}\) and the y-intercept \(b\) is \(\frac{9}{32}\).
Plotting the Line
To plot the line, start at the y-intercept (\(0, \frac{9}{32}\)). Since \(\frac{9}{32}\) is approximately \(0.28125\), you can estimate this point on the y-axis.
Next, use the slope \(-\frac{1}{32}\):
- For every increase of 32 units in \(x\), \(y\) decreases by 1 unit.
Example Points
- Y-Intercept: (0, \(0.28125\))
- Another Point: Move 32 units to the right (to \(x = 32\)), and decrease \(y\) by 1: \[ (32, 0.28125 - 1) = (32, -0.71875) \]
These two points can be used to draw the line.
Conclusion
Choose the graph that accurately reflects these calculations and includes points around (0, 0.28125) and (32, -0.71875). Based on the provided responses, make sure the coordinates of the plotted points adhere to a similar pattern as determined.
