Responses

A coordinate plane ranges from negative 9 to 9 in unit increments on the x-axis and from 11 to negative 11 in unit increments on the y-axis. A line with arrows at both the ends joins two plotted points and extends beyond. The coordinates of the plotted points are: left parenthesis 0 comma 0 right parenthesis and left parenthesis 2 comma 1 right parenthesis.

To graph the equation \( 9 - x = 32y \) in slope-intercept form, we need to rearrange the equation into the form \( y = mx + b \), where \( m \) is the slope and \( b \) is the y-intercept.

Starting with the original equation:

\[ 9 - x = 32y \]

First, isolate \( y \):

\[ 32y = 9 - x \]

Next, divide everything by 32 to solve for \( y \):

\[ y = \frac{9 - x}{32} \]

This simplifies to:

\[ y = -\frac{1}{32}x + \frac{9}{32} \]

Now we can see that:

  • The slope \( m = -\frac{1}{32} \)
  • The y-intercept \( b = \frac{9}{32} \)

To graph the equation, we start by plotting the y-intercept at \( (0, \frac{9}{32}) \). We can also plot another point using the slope. For every increase of 32 in \( x \), \( y \) will decrease by 1 (since the slope is negative).

Using the slope, we can calculate the coordinates of a second point. Starting at the y-intercept, let's pick an \( x \) value. If \( x = 32 \):

\[ y = -\frac{1}{32}(32) + \frac{9}{32} = -1 + \frac{9}{32} = \frac{9 - 32}{32} = \frac{-23}{32} \]

Now we have two points:

  1. \( (0, \frac{9}{32}) \)
  2. \( (32, -\frac{23}{32}) \)

You can continue graphing the line using the identified points.

Among the given options, the correct graph is the one that shows a line with these coordinates correctly represented. If you have the opportunity to match with observed plotted points, then look for points that suggest this downward slope and correspond to the y-intercept found.

If the visual descriptions you've provided do not represent these points correctly, you may need to choose the one that seems closest or has a slope that appears reasonable given the format. Otherwise, you could graph based on my points described above.
