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=5#
#rArry=5x+blarrcolor(blue)"is the partial equation"#
#"to find b substitute "(1,9)" into the partial equation"#
#9=5+brArrb=9-5=4#
#rArry=5x+4larrcolor(red)"is the equation of the line"#
