slope = #1/2#
y-intercept = #2.3#
x-intercept = #-4.6#

From the slope-intercept formula:
#y = mx + b#

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

so

the slope is #1/2#

the y-intercept is 2.3

to find x-intercept make #y = 0# and solve

so

#0 = 1/2x+2.3#

solve for x

subtract 2.3 from both sides

#-2.3 = 1/2x#

multiply both sides by 2

#-4.6 = x#

x-intercept #= -4.6#
