Question

Right equation of the line that passes through (-1,5) and has a slope of 3 in point slope form.

Answer 1

$\bf \begin{array}{ccccccccc} &&x_1&&y_1\\ % (a,b) &&(~ -1 &,& 5~) \end{array} \\\\\\ % slope = m slope = m\implies 3 \\\\\\ % point-slope intercept \stackrel{\textit{point-slope form}}{y- y_1= m(x- x_1)}\implies y-5=3[x-(-1)] \implies y-5=3(x+1)$
