Answer:
e) 1 / 2
f) -3 / 2
Step-by-step explanation:
e) line passing through points (1,1) (3,2)
you can count coordinates by blocks
slope = (y2 - y1 ) / (x2 - x1)
= (2 - 1) / (3 -1 )
= 1 / 2
f) line passing through points (0,0) (-2,3)
slope = (y2 - y1 ) / (x2 - x1)
= (3 - 0) / (-2 - 0)
= 3 / -2
= -3 / 2
