Start by expressing the equation in point-slope form; then convert to standard form.

Point-slope form
#(y-y_1) = m(x-x_1)#
#(y-5) = 9(x-(-4))#

Standard form
#Ax+By=C#
#(y-5)=9(x-(-4))#
#rarr y-5 = 9x+36#
#rarr (-9)x+(1)y=41#
or
#9x -y = -41 #
#" since some definitions of standard form require the coefficent of "x" to be a non-negative integer"#
