Help help, thank you-

y=-1/3x+1

Step-by-step explanation:

Perpendicular lines have opposite slopes, which means you take the opposite reciprocal of it (flip the fraction and use the opposite sign).

3 written as a fraction is 3/1, so to make it the opposite make it -1/3x

To get the equation of the line, use point slope shown below:

y-y1=m(x-x1)

y+2=-1/3(x-9)

y+2=-1/3x+3

y=-1/3x+1

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s
