What is the equation of the line that is parallel to the given line and passes through the point [tex]$(-2,2)$[/tex]?

A. [tex]$y = \frac{1}{5}x + 4$[/tex]
B. [tex]$y = \frac{1}{5}x + \frac{12}{5}$[/tex]
C. [tex]$y = -5x + 4$[/tex]
D. [tex]$y = -5x + \frac{12}{5}$[/tex]



Answer :

To find the equation of the line that is parallel to a given line and passes through a specific point, we need to follow these steps:

1. Identify the slope of the given line:
Since we are looking for a parallel line, it will have the same slope as the given line. Here, the given slope is [tex]\(\frac{1}{5}\)[/tex].

2. Use the point-slope form of the line equation:
The point-slope form is [tex]\(y - y_1 = m(x - x_1)\)[/tex], where [tex]\(m\)[/tex] is the slope and [tex]\((x_1, y_1)\)[/tex] is the point given. In this case, the point is [tex]\((-2, 2)\)[/tex].

3. Substitute the slope and point into the point-slope form:
[tex]\[ y - 2 = \frac{1}{5}(x - (-2)) \][/tex]

4. Simplify the equation:
[tex]\[ y - 2 = \frac{1}{5}(x + 2) \][/tex]

First distribute the slope:
[tex]\[ y - 2 = \frac{1}{5}x + \frac{1}{5} \cdot 2 \][/tex]

[tex]\[ y - 2 = \frac{1}{5}x + \frac{2}{5} \][/tex]

5. Isolate y to convert the equation to slope-intercept form ([tex]\(y = mx + b\)[/tex]):
[tex]\[ y = \frac{1}{5}x + \frac{2}{5} + 2 \][/tex]

6. Add the constant term on the right side:
[tex]\[ y = \frac{1}{5}x + \frac{2}{5} + \frac{10}{5} \][/tex]

[tex]\[ y = \frac{1}{5}x + \frac{12}{5} \][/tex]

Therefore, the equation of the line that is parallel to the given line and passes through the point [tex]\((-2, 2)\)[/tex] is:

[tex]\[ y = \frac{1}{5}x + \frac{12}{5} \][/tex]

Hence, the correct option is:

[tex]\[ y = \frac{1}{5}x + \frac{12}{5} \][/tex]
