Answer:

See the answer below....

Explanation:

If the equation of a straight line is written in the form #color(red)(ul(bar(|color(black)(y=mx+c)|#,then the slope of the line is #color(red)(m# and #Y# intercept is #color(red)(c#.

#x-y+7=0#
#=>y=x+7#

Comparing we get, the slope of the line is #color(red)(1#

Hope that helps...

Answer:

#"slope "=1#

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 "x-y+7=0" into this form"#

#"add y to both sides"#

#xcancel(-y)cancel(+y)+7=0+y#

#rArry=x+7larrcolor(blue)"in slope-intercept form"#

#rArr"slope "=1#
