## 📌 General Rules for Graphing:

- Equations (like y = mx + b) → Draw a solid line.
- Inequalities with > or < → Draw a dashed line, then shade the region that satisfies the inequality.
- Inequalities with ≥ or ≤ → Draw a solid line, then shade the region that satisfies the inequality.
- To graph a line, find two points (often the x- and y-intercepts or use slope-intercept form).

# 🔢 Problem 1: `y > -x - 5`

Step-by-step:


1. Graph the boundary line: `y = -x - 5`
- This is in slope-intercept form: slope = -1, y-intercept = -5.
- Plot point (0, -5).
- From there, go down 1, right 1 → next point (1, -6).
- Draw a dashed line (because it’s >, not ≥).

2. Shade the region: Test point (0, 0):
- Plug into inequality: `0 > -0 - 5` → `0 > -5` → TRUE.
- So shade above the line (where y-values are greater).

Final graph: Dashed line with slope -1, y-int -5; shade above.

# 🔢 Problem 2: `y = -3x - 3`

Step-by-step:


1. Slope-intercept form: slope = -3, y-intercept = -3.
2. Plot (0, -3).
3. From there, go down 3, right 1 → (1, -6).
4. Draw a solid line (it’s an equation, not inequality).

Final graph: Solid line through (0,-3) and (1,-6).

# 🔢 Problem 3: `x < -5`

Step-by-step:


1. This is a vertical line at x = -5.
2. Since it’s `<`, draw a dashed vertical line at x = -5.
3. Shade to the left of the line (because x-values less than -5 are to the left).

Final graph: Dashed vertical line at x = -5; shade left side.

# 🔢 Problem 4: `x - 4y = 0`

Step-by-step:


1. Solve for y to get slope-intercept form:
```
x - 4y = 0
→ -4y = -x
→ y = (1/4)x
```
2. Slope = 1/4, y-intercept = 0 → line passes through origin (0,0).
3. Another point: when x=4, y=1 → (4,1).
4. Draw a solid line (equation).

Final graph: Solid line through (0,0) and (4,1).

# 🔢 Problem 5: `5x - 3y ≤ -15`

Step-by-step:


1. First, graph the boundary: `5x - 3y = -15`
- Find intercepts:
- x-intercept: set y=0 → 5x = -15 → x = -3 → (-3, 0)
- y-intercept: set x=0 → -3y = -15 → y = 5 → (0, 5)
- Plot (-3, 0) and (0, 5). Draw solid line (≤).

2. Shade the region: Test point (0,0):
- Plug in: `5(0) - 3(0) ≤ -15` → `0 ≤ -15` → FALSE.
- So shade the opposite side of (0,0) — the side that includes (-3,0) and (0,5).

Final graph: Solid line through (-3,0) and (0,5); shade below/left side (away from origin).

---

# 🔢 Problem 6: `y = 3x - 4`

Step-by-step:


1. Slope = 3, y-intercept = -4.
2. Plot (0, -4).
3. From there, go up 3, right 1 → (1, -1).
4. Draw solid line.

Final graph: Solid line through (0,-4) and (1,-1).

## 🖍️ How to Sketch on Grid Paper:

For each problem:

1. Draw your axes (x and y) clearly.
2. Plot two points for each line.
3. Connect them with straight line (solid/dashed as needed).
4. For inequalities, pick a test point (usually (0,0)) to determine shading direction.
5. Shade lightly with pencil or use arrows if coloring isn't allowed.
