You can put this solution on YOUR website! a) Find the slope,if any, of the line through the points (-4,7) and 6,7)
b) Find the slope if any of the line parallel to the line through points (-2,7) and (4,3)
c) Find the slope if any of the line perpendicular to the line through the points
(2,-7) and (3,4).
d) The equation of the line with slope 2/5 and y intercept (0,-5)
------------------
a) Slope m = (y2-y1)/(x2-x1)
m = 0/10
m = 0 (parallel to the X-axis.
-----------
b) m = (7-3)/(-2-4)
m = -2/3
All parallel lines have the same slope.
c) Perpendicular lines have a negative inverse slope
m = +3/2
------------
d) Use y = mx + b
y = (2/5)x -5
5y = 2x - 25
2x - 5y = 25
