#"slope "=-3" and y-intercept "=-5#

Explanation:

#"the equation of a line in "color(blue)"slope-intercept form "# is.

#color(red)(bar(ul(|color(white)(2/2)color(black)(y=mx+b)color(white)(2/2)|)))#

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

#y=-3x-5" is in this form"#

#rArr"slope "=m=-3" and y-intercept "=b=-5#

The slope is #-3# and the #y#-intercept is #-5#.

Explanation:

The equation is in slope-intercept form

#y=mx+b#

where #m# is the slope, #x# is the #x# value, and #m# is the #y#-intercept. The number before the #x# variable is the slope, so #-3#. The number added is #(-5)#, so #5# is subtracted or #(-5)# is added.
