Right equation of the line that passes through (-1,5) and has a slope of 3 in point slope form.
MrRissso [65]
\bf \begin{array}{ccccccccc}
&&x_1&&y_1\\
%  (a,b)
&&(~ -1 &,& 5~)
\end{array}
\\\\\\
% slope  = m
slope =  m\implies 3
\\\\\\
% point-slope intercept
\stackrel{\textit{point-slope form}}{y- y_1= m(x- x_1)}\implies y-5=3[x-(-1)]
\implies 
y-5=3(x+1)

If you live 1.5 miles from school and you walk at a rate of 3mph, when should you leave home in order to arrive at school by 9:0
storchak [24]
<h3>Answer is  8:30 </h3>

Work Shown:

time = distance/speed

time = (1.5 miles)/(3 mph)

time = (1.5/3) hours

time = 0.5 hours

time = 30 minutes

It takes 30 minutes to walk to school, so you should leave a half hour before 9:00. Subtracting 30 minutes from 9:00 gets you to 8:30. If anything, you should start a little bit before 8:30 just in case something might slow you down for one reason or another.
