I. Determine the slope of the following lines:
II. Find the slope of the line passing through the given points:
III. Find the slope of a line parallel (same slope as the one you find) to the line passing through the given points:
IV. Find the slope of the line perpendicular (negative reciprocal of the slope you find) to the line passing through the given points:
V. Find the value of c: (hint: plot point on a graph and move the slope)
17. a line through points (5,4) and (7, c) has a slope of m= -2 c = _0__

18. a line through points (4,2) and (c, -2) has a slope of m = 2/3 c =

VI. Write an equation of a line that: (hint: find slope, then use point slope form to write the equation of the line.
19. Contains the point (5, 4) and is parallel to the line y = 2x – 7
20. That is perpendicular to y= 2x – 7 and passes through (-2,-4)
