Answer:

#"slope "=3," y-intercept "=2#

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"#

#"rearrange "3x-y=-2" into this form"#

#"add "y" to both sides"#

#3xcancel(-y)cancel(+y)=y-2#

#rArr3x=y-2#

#"add 2 to both sides"#

#rArr3x+2=ylarrcolor(blue)"in slope-intercept form"#

#"with slope "=3" and y-intercept "=2#
