Which equation represents a line which is parallel to the line y, equals, minus, start fraction, 3, divided by, 5, end fraction, x, minus, 7*y*=−53​*x*−7?

Answer

Multiple Choice Answers

3, x, plus, 5, y, equals, 153*x*+5*y*=15

3, y, minus, 5, x, equals, 63*y*−5*x*=6

5, x, plus, 3, y, equals, 125*x*+3*y*=12

3, x, minus, 5, y, equals, minus, 303*x*−5*y*=−30

To solve this, we first need to understand the concept of parallel lines. Two lines are parallel if they have the same slope.

The given equation is:

\[
y = -\frac{3}{5}x - 7
\]

Here, the slope is \(-\frac{3}{5}\).

Now, let’s analyze each of the multiple-choice options and convert them into slope-intercept form \(y = mx + b\), where \(m\) represents the slope:

### 1. \(3x + 5y = 15\)
Solve for \(y\):

\[
5y = -3x + 15
\]
\[
y = -\frac{3}{5}x + 3
\]
The slope is \(-\frac{3}{5}\), so this line is **parallel** to the given line.

### 2. \(3y - 5x = 6\)
Solve for \(y\):

\[
3y = 5x + 6
\]
\[
y = \frac{5}{3}x + 2
\]
The slope is \(\frac{5}{3}\), so this line is **not parallel**.

### 3. \(5x + 3y = 12\)
Solve for \(y\):

\[
3y = -5x + 12
\]
\[
y = -\frac{5}{3}x + 4
\]
The slope is \(-\frac{5}{3}\), so this line is **not parallel**.

### 4. \(3x - 5y = -30\)
Solve for \(y\):

\[
-5y = -3x - 30
\]
\[
y = \frac{3}{5}x + 6
\]
The slope is \(\frac{3}{5}\), so this line is **not parallel**.

### Conclusion:
The equation that represents a line parallel to \(y = -\frac{3}{5}x - 7\) is **Option 1: \(3x + 5y = 15\)**.
