Question

what is the point-slope form of a line that has a slope of \\(\frac{1}{2}\\) and passes through point \\((-7, 2)\\)?

\\(2 - y = \frac{1}{2}(7 - x)\\)

\\(7 - y = \frac{1}{2}(-2 - x)\\)

\\(y - 7 = \frac{1}{2}(x - 2)\\)

\\(y - 2 = \frac{1}{2}(x - (-7))\\)

<reasoning>

Identify the point-slope formula

\[
y - y_1 = m(x - x_1)
\]

Substitute the given values

\[

$$\begin{aligned} &m = \frac{1}{2}\\ &(x_1, y_1) = (-7, 2)\\ &y - 2 = \frac{1}{2}(x - (-7)) \end{aligned}$$

\]
