Which equation shows the point-slope form of the line that passes through [tex]$(3,2)$[/tex] and has a slope of [tex]$\frac{1}{3}$[/tex]?

A. [tex]$y + 2 = \frac{1}{3}(x + 3)$[/tex]
B. [tex]$y - 2 = \frac{1}{3}(x - 3)$[/tex]
C. [tex]$y + 3 = \frac{1}{3}(x + 2)$[/tex]
D. [tex]$y - 3 = \frac{1}{3}(x - 2)$[/tex]



Answer :

Certainly! To determine the equation showing the point-slope form of the line that passes through the point [tex]\((3,2)\)[/tex] and has a slope of [tex]\(\frac{1}{3}\)[/tex], we can follow a systematic approach using the point-slope form of a line.

### Step-by-Step Solution

1. Recall the Point-Slope Form:
The point-slope form of a line is given by the formula:
[tex]\[ y - y_1 = m(x - x_1) \][/tex]
where [tex]\((x_1, y_1)\)[/tex] is a point on the line and [tex]\(m\)[/tex] is the slope.

2. Substitute the Given Values:
- The point we have is [tex]\((3, 2)\)[/tex], so [tex]\(x_1 = 3\)[/tex] and [tex]\(y_1 = 2\)[/tex].
- The slope [tex]\(m\)[/tex] is given as [tex]\(\frac{1}{3}\)[/tex].

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

3. Match the Format:
Compare the obtained equation [tex]\(y - 2 = \frac{1}{3}(x - 3)\)[/tex] with the given choices:
- [tex]\(y + 2 = \frac{1}{3}(x + 3)\)[/tex]
- [tex]\(y - 2 = \frac{1}{3}(x - 3)\)[/tex]
- [tex]\(y + 3 = \frac{1}{3}(x + 2)\)[/tex]
- [tex]\(y - 3 = \frac{1}{3}(x - 2)\)[/tex]

It is clear that the equation [tex]\(y - 2 = \frac{1}{3}(x - 3)\)[/tex] matches our derived equation.

### Conclusion

Hence, the correct equation showing the point-slope form of the line passing through [tex]\((3, 2)\)[/tex] with a slope of [tex]\(\frac{1}{3}\)[/tex] is
[tex]\[ \boxed{y - 2 = \frac{1}{3}(x - 3)} \][/tex]
