Step-by-step solution for: Graphing Linear Equation Worksheets
It looks like you've uploaded a worksheet titled "Graphing a Line" that asks students to:
1. Rewrite each equation in slope-intercept form (i.e., $ y = mx + b $).
2. Then, graph the line on the provided coordinate plane.
Since I can't view images directly, I’ll help you solve this type of problem step-by-step based on the typical format of such worksheets. Let’s go through how to approach each problem.

The slope-intercept form of a linear equation is:
$$
y = mx + b
$$
Where:
- $ m $ = slope
- $ b $ = y-intercept
To graph a line:
1. Plot the y-intercept ($ b $) on the y-axis.
2. Use the slope ($ m $) to find another point (rise over run).
3. Draw a straight line through the points.

Let’s assume one of the equations is:
> Problem 1: $ 3y - 15 = -6x $
#### Step 1: Solve for $ y $
$$
3y = -6x + 15
$$
Divide both sides by 3:
$$
y = -2x + 5
$$
Now it's in slope-intercept form:
- Slope $ m = -2 $
- Y-intercept $ b = 5 $
#### Step 2: Graph the Line
1. Start at $ (0, 5) $ — this is the y-intercept.
2. Use slope $ -2 $ → go down 2 units, right 1 unit to get to $ (1, 3) $.
3. Draw a line through these two points.

Here are likely equations from your worksheet (based on common problems):
---
#### 1. $ 3y - 15 = -6x $
$$
3y = -6x + 15 \Rightarrow y = -2x + 5
$$
- Slope: $ -2 $
- Y-intercept: $ 5 $
---
#### 2. $ -3x + 6y = 12 $
$$
6y = 3x + 12 \Rightarrow y = \frac{1}{2}x + 2
$$
- Slope: $ \frac{1}{2} $
- Y-intercept: $ 2 $
---
#### 3. $ 5x - 2 = 2y $
$$
2y = 5x - 2 \Rightarrow y = \frac{5}{2}x - 1
$$
- Slope: $ \frac{5}{2} $
- Y-intercept: $ -1 $
---
#### 4. $ -4x - 6y = 3 $
$$
-6y = 4x + 3 \Rightarrow y = -\frac{2}{3}x - \frac{1}{2}
$$
- Slope: $ -\frac{2}{3} $
- Y-intercept: $ -\frac{1}{2} $
---
#### 5. $ -3y + 9x = 30 $
$$
-3y = -9x + 30 \Rightarrow y = 3x - 10
$$
- Slope: $ 3 $
- Y-intercept: $ -10 $
---
#### 6. $ -4y - 8x = 4 $
$$
-4y = 8x + 4 \Rightarrow y = -2x - 1
$$
- Slope: $ -2 $
- Y-intercept: $ -1 $
---
#### 7. $ -3x + 6 = 3y $
$$
3y = -3x + 6 \Rightarrow y = -x + 2
$$
- Slope: $ -1 $
- Y-intercept: $ 2 $
---
#### 8. $ 3x - 2y = 14 $
$$
-2y = -3x + 14 \Rightarrow y = \frac{3}{2}x - 7
$$
- Slope: $ \frac{3}{2} $
- Y-intercept: $ -7 $
---
#### 9. $ -6y + 6 = x $
$$
-6y = x - 6 \Rightarrow y = -\frac{1}{6}x + 1
$$
- Slope: $ -\frac{1}{6} $
- Y-intercept: $ 1 $
---
For each equation:
1. Plot the y-intercept on the graph.
2. Use the slope to find a second point.
- Example: If slope = $ \frac{3}{2} $, go up 3, right 2.
- If slope = $ -\frac{1}{6} $, go down 1, right 6.
3. Draw a straight line through the points.
---
- Always rewrite in $ y = mx + b $ before graphing.
- Double-check algebra (especially signs and division).
- Use a ruler to draw clean lines.
- Label the graph if required.

If you can describe or list the exact equations from the worksheet, I can give you the exact answers and graphs for each.
Alternatively, if you want me to generate a completed version of the worksheet, let me know — I can provide the rewritten equations and instructions for plotting each graph.
