Given the point #(-5,-2)# and the slope #(-3)# we can easily write the linear equation in slope-point form and then convert it to standard form.

Slope-Point Form
#(y-y_1) = m(x-x_1)# for a slope of #m# and a point #(x_1,y_1)#
becomes
#(y-(-2))= (-3)(x-(-5))#
or
#y+2 = (-3)(x+5)#

Standard Form
Standard form of a linear equation is
#Ax+By=C# with #A>=0 and AepsilonZZ#
#y+2 = (-3)(x+5)#
#rarr y+2 = -3x -15#

#rarr 3x+1y = -17#

which is in standard form
