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=-1/4#
#rArry=-1/4x+blarrcolor(blue)"is the partial equation"#
#"to find b substitute "(-7,-1)" into the partial equation"#
#-1=7/4+brArrb=-4/4-7/4=-11/4#
#rArry=-1/4x-11/4larrcolor(red)"in slope-intercept form"#
