Question 1007642
the slope and intercept form of linear equation is:

{{{y=mx+b}}} where {{{m}}} is a slope and {{{b}}} is y-intercept

you are given {{{y=7}}}

if you compare it to {{{y=mx+b}}}, you see that {{{mx=0}}}=> slope {{{highlight(m=0)}}} for any value of {{{x}}} and {{{b=7}}}

so, you have a horizontal line which  slope is {{{highlight(0)}}} and  y-intercept is {{{highlight(7)}}}
