Step-by-step solution for: Graphing Linear Equations Worksheets
The image you uploaded appears to be a worksheet titled "Graphing Linear Equations." The task involves completing certain steps and then using the results to graph a line. Below, I will outline how to solve such problems step by step.
---
1. Identify the Equation:
- The equation is typically given in one of the following forms:
- Slope-intercept form: \( y = mx + b \)
- Standard form: \( Ax + By = C \)
- Point-slope form: \( y - y_1 = m(x - x_1) \)
2. Find Key Points:
- Intercepts:
- x-intercept: Set \( y = 0 \) and solve for \( x \).
- y-intercept: Set \( x = 0 \) and solve for \( y \).
- Additional Points:
- Choose other values for \( x \) or \( y \) and solve for the corresponding variable to get more points on the line.
3. Plot the Points:
- Plot the intercepts and any additional points you calculated on a coordinate plane.
4. Draw the Line:
- Connect the points with a straight line. Ensure the line extends beyond the plotted points if necessary.
5. Verify:
- Check if the line passes through all the points you plotted.

#### Given Equation:
Let's assume the equation is \( y = 2x + 3 \).
#### Step 1: Identify the Equation
The equation is already in slope-intercept form (\( y = mx + b \)), where:
- \( m = 2 \) (slope)
- \( b = 3 \) (y-intercept)
#### Step 2: Find Key Points
##### a) Find the y-intercept:
- The y-intercept occurs when \( x = 0 \).
- Substitute \( x = 0 \) into the equation:
\[
y = 2(0) + 3 = 3
\]
- So, the y-intercept is \( (0, 3) \).
##### b) Find the x-intercept:
- The x-intercept occurs when \( y = 0 \).
- Substitute \( y = 0 \) into the equation:
\[
0 = 2x + 3
\]
\[
2x = -3
\]
\[
x = -\frac{3}{2}
\]
- So, the x-intercept is \( \left( -\frac{3}{2}, 0 \right) \).
##### c) Find Additional Points:
- Choose another value for \( x \), say \( x = 1 \):
\[
y = 2(1) + 3 = 5
\]
- Point: \( (1, 5) \)
- Choose another value for \( x \), say \( x = -1 \):
\[
y = 2(-1) + 3 = 1
\]
- Point: \( (-1, 1) \)
#### Step 3: Plot the Points
- Plot the following points on the coordinate plane:
- \( (0, 3) \) (y-intercept)
- \( \left( -\frac{3}{2}, 0 \right) \) (x-intercept)
- \( (1, 5) \)
- \( (-1, 1) \)
#### Step 4: Draw the Line
- Connect the points with a straight line. Extend the line in both directions.
#### Step 5: Verify
- Ensure the line passes through all the plotted points.

If the worksheet asks for specific points or the final graph, you would provide the coordinates of the points and/or the graph itself. For example:
- Points: \( (0, 3) \), \( \left( -\frac{3}{2}, 0 \right) \), \( (1, 5) \), \( (-1, 1) \)
- Graph: A straight line passing through these points.
If you can provide the exact equation or specific instructions from your worksheet, I can tailor the solution further!
Boxed Final Answer (if required):
\[
\boxed{(0, 3), \left( -\frac{3}{2}, 0 \right), (1, 5), (-1, 1)}
\]
