#### Explanation:

#"the equation of a line in "color(blue)"standard form"# is.

#color(red)(bar(ul(|color(white)(2/2)color(black)(Ax+By=C)color(white)(2/2)|)))#

where A is a positive integer and B, C are integers.

#"first express the equation in "color(blue)"point-slope form"#

#color(red)(bar(ul(|color(white)(2/2)color(black)(y-y_1=m(x-x_1))color(white)(2/2)|)))#

where m represents the slope and# (x_1,y_1)" a point on the line"#

#"here " m=-3/2" and " (x_1,y_1)=(-2,4)#

#rArry-4=-3/2(x+2)larrcolor(red)" in point-slope form"#

#"rearrange terms into standard form"#

#y-4=-3/2x-3#

#rArr3/2x+y=1larr" multiply through by 2"#

#rArr3x+2y=2larrcolor(red)" in standard form"#
