how to find slope of line (m)
=y2 - y1/x2 - x1
7. there, (16,2) occupies the x1 (16) and y1 (2) positions.
and, (32,4) occupies the x2 (32) and y2 (4) positions.
ok, enter:
m = y2 - y1/ x2 - x1
=4 - 2 / 32 - 16
=2/16
= 1/8
8. there, (-2,17) occupies the x1 (-2) and y1 (17) positions.
and, (-1,5) occupies the x2 (-1) and y2 (5) positions.
ok, enter:
m= y2 - y1/ x2 - x1
=5 - 17/ -1 - (-2)
=5 - 17 / -1 + 2
= -12 / 1
= -12
FINALLY FOUND, MODERATOR!!!
