Linear Equations in Point-Slope Form

Write the equation for the line in point-slope form.

3. The slope is \(\begin{align*}\frac{1}{3}\end{align*}\); the \(\begin{align*}y-\end{align*}\)intercept is –4.

4. The slope is \(\begin{align*}-\frac{1}{10}\end{align*}\) and contains the point (10, 2).

7. The line contains the points (–2, 3) and (–1, –2).

Write each equation in slope-intercept form.

14. \(\begin{align*}y-2=3(x-1)\end{align*}\)

15. \(\begin{align*}y+4=\frac{-2}{3}(x+6)\end{align*}\)
