Slope: #3#
y-intercept: #(-5)#

Explanation:

Any linear equation in the form
#color(white)("XXX")y = color(red)(m)x+color(blue)(b)#
is in a form called the "slope-intercept form" with a slope of #color(red)(m)# and a y-intercept of #color(blue)(b)#

#y=3x-5# is almost in this form.

Re-writing as #y =color(red)(3)x + color(blue)((-5))# places it in "slope-intercept form"
with slope #color(red)(3)# and y-intercept #color(blue)((-5))#
