keeping in mind that perpendicular lines have negative reciprocal slopes, let's check for the slope of the equation above

well then therefore

so we're really looking for the equation of a line with slope of -1/3 and that passes through (1, -3 )

Answer:
A.
Step-by-step explanation:
41.4 wph because if you divide 207 by 5 you get 41.4
B
For example if it has been 2 months (l=1.25 times 2) the length would be 1.5 cm
