1. Will the following lines be parallel, perpendicular, or neither?

Line 1: through (-2, 6) and (2, 8)

Line 2: through (0, -4) and (5, -3)

2. Find k given a line passes through (3, k) and (k, -1) and has a slope of 3.

3. Write the equation of the line in slope-intercept form that passes through the point: (8, 5), (11, 4)

4. Write the equation of the line that passes through (3, -5) and is perpendicular to the line through (1, 4) and (3, -2).
