Question

y=
–
3
x–5

1-8 x and y axis

Answer 1

It looks like you've provided an equation of a line, which is \( y = -3x - 5 \). This is the equation in slope-intercept form (y = mx + b), where:

- The **slope** (m) is -3, which means that for every 1 unit increase in \( x \), \( y \) decreases by 3 units.
- The **y-intercept** (b) is -5, which means the line crosses the y-axis at \( (0, -5) \).

To analyze this line with respect to the x-axis and y-axis, we can:

### 1. Find the x-intercept:
To find the x-intercept, we set \( y = 0 \) and solve for \( x \):

\[
0 = -3x - 5
\]
\[
3x = -5
\]
\[
x = -\frac{5}{3} \approx -1.67
\]

So the x-intercept is approximately \( \left(-\frac{5}{3}, 0\right) \) or \( (-1.67, 0) \).

### 2. Summary of Intercepts:
- **Y-intercept:** \( (0, -5) \)
- **X-intercept:** \( \left(-\frac{5}{3}, 0\right) \) or approximately \( (-1.67, 0) \)

### 3. Sketching the Line:
To graph the line:
- Plot the y-intercept \( (0, -5) \).
- Plot the x-intercept \( (-1.67, 0) \).
- Draw a straight line through these points, extending in both directions.

### Example Points
You can also calculate additional points to help sketch the line:

- When \( x = 1 \):
\[
y = -3(1) - 5 = -3 - 5 = -8 \quad (1, -8)
\]

- When \( x = -2 \):
\[
y = -3(-2) - 5 = 6 - 5 = 1 \quad (-2, 1)
\]

Plotting these additional points can provide more accuracy when drawing the line.
