Question
the point-slope form of a line that has a slope of \\(\frac{2}{3}\\) and passes through point \\((6, 0)\\) is shown below.
\\y - 0 = \frac{2}{3}(x - 6)\\
what is the equation in slope-intercept form?
\\(y = \frac{2}{3}x - 12\\)
\\(y = \frac{2}{3}x - 6\\)
\\(y = \frac{2}{3}x - 4\\)
\\(y = \frac{2}{3}x - 8\\)

<reasoning>
Distribute the slope on the right side
\[
y - 0 = \frac{2}{3}(x - 6)
\]
\[
y - 0 = \frac{2}{3}x - \frac{2}{3}(6)
\]
Simplify the constant term
\[
\frac{2}{3}(6) = 4
\]
\[
y = \frac{2}{3}x - 4
\]
