Question 1070943
The line you want will have slope  {{{-2/(4/3)=-2*3/4=highlight_green(-3/2)}}}, because this is the negative reciprocal of the given line so that both lines be perpendicular.


Equation for line of that found slope passing through the given point, in the point-slope form:
{{{highlight(y+3=-(3/2)(x+1))}}}
