Answer:

The y-intercept is #-5# or #(0, -5)#

The x-intercept is #-10# or #(-10, 0)#

Explanation:

Because this equation is in slope-intercept form:

#y = mx + c# where #m# is the slope and #c# is the y-intercept of #(0, c)#.

So for this problem the y-intercept is #-5# or #(0, -5)#

To find the x-intercept we need to set #y# to #0# and solve for #x#:

#0 = -1/2x - 5#

#0 + 5 = -1/2x - 5 + 5#

#5 = -1/2x - 0#

#5 = -1/2x#

#5 xx -2 = -1/2x xx -2#

#-10 = (-2)/(-2)x#

#-10 = 1x#

#-10 = x#
