#y=-2x+8#

Explanation:

We have given

#y=mx+n# where #m# denotes the slope and #n# is the y-intercept, so
#m=-2# and #n=8#

#2x+y=8#

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"#

#"to begin with obtain the equation in "color(blue)"slope-intercept form"#

#•color(white)(x)y=mx+b#

#"where m is the slope and b the y-intercept"#

#"here "m=-2" and "b=8#

#y=-2x+8larrcolor(red)"in slope-intercept form"#

#"add "2x" to both sides"#

#2x+y=8larrcolor(red)"in standard form"#
