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=4#
#rArry=4x+blarrcolor(blue)"is the partial equation"#
#"to find b substitute "(-4,-7)" into the partial equation"#
#-7=-16+brArrb=-7+16=9#
#rArry=4x+9larrcolor(red)"is the equation"#
