Question 1155614: Given the points ( 4, -3) and ( 2, 2) answer the following.
a. Find the slope of the line, L1, that goes through the points ( 4, -3) and ( 2, 2).
b. Write the equation of the line, L1. Write in slope intercept form.
c. Find the slope of the line, L2, that is perpendicular to L1.
d. Write the equation of the line, L2, that goes through the point ( -3, 5 ).

a. Find the slope of the line, L1, that goes through the points
( ,  ) and (  , ).
the slope of the line is:
b. Write the equation of the line, L1. Write in slope intercept form.
plug in a slope and coordinates of one point, ( , )
 ........solve for 
=> equation is:
c. Find the slope of the line, L2, that is perpendicular to L1.
perpendicular lines have slopes negative reciprocal to each other
if the slope of the line L1 is  , the slope of the line L2 will be
d. Write the equation of the line, L2, that goes through the point ( ,  ).
 ........plug in given point
=> equation is:
