Explanation:
#"the equation of a line in "color(blue)"slope-intercept form"# is.
#•color(white)(x)y=mx+b#
#"where m is the slope and b the y-intercept"#
#"here "m=-2#
#rArry=-2x+blarrcolor(blue)"is the partial equation"#
#"to find b substitute "(-3,1)" into the partial equation"#
#1=6+brArrb=1-6=-5#
#rArr"y-intercept "=-5#
graph{-2x-5 [-10, 10, -5, 5]}
