1. Find the slope of the line passing through the points (-9,-4) and (0,-4).
2. Find the slope of the line passing through the points (-7,-4) and (-1,-10).
3. Determine which two equations represent parallel lines.
(a). y=5/3x + 4 (b). y= -3/5x -7 (c). y=2x + 8 (d) y=2x -4
4. Find the y- intercept for:
-x + 3y =15
5.Determine which two equations represent perpendicular lines.
(a) y= 4/7x - 3 (b) y=3x-4/7 (c) y= -1/3x + 4/7 (d) y= 1/3x - 4/7
6. Write an equation of the line passing through (4,4) and (4,2).
7. Write the equation of the line which has y-intercept (0,5) and is perpendicular to the line with equatin y= -3x+1.
8.Rewrite the equation 2x-3y= -6 as a function of x.
