So, we have:

Collect Like Terms



Answer:
Step-by-step explanation:
point-slope formula is asked for [y-y1 = m(x-x1]
where the given point, P=(x1,y1) = (-4,6)
and the slope , m is given as 3/2
so plug those into the formula
y-6=3/2(x-(-4))
y-6=3/2(x+4)
voila .. you are done :)
Use distance, time and speed formula.
speed = 4m/mins
distance = 5.12 meter
time = distance/speed
time = 5.12/4
time = 1.28 minutes
It walks 1.28 minutes
hope this help you !!!!!!!!!
