Answer :

y + 2 = 9

y = 7

y = zero-x + 7

The y-intercept is 7.
The slope is zero.

The graph is a horizontal line. That's the meaning of zero slope.
It crosses the y-axis at 7, and it's always 7 units above the x-axis.
The line is parallel to the x-axis, and never crosses it.

[tex]if\ y=mx+b,\ \ \ then\ \ \ m\ \ is\ the\ slope\ \ \ and\ \ \ b\ \ is\ the\ intercept\\------------------------------\\ y+2=9\\\\y=9-2\\\\y=7\ \ \ \Rightarrow\ \ \ the\ slope\ \ \ \ m=0\\\\.\ \ \ \ \ \ \ \ \ \Rightarrow \ \ \ the\ intercept\ \ \ b=7[/tex]
