What is the intercept? what is the slope? y+2=9

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.

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

Graph the function. For the function whose graph is shown below, which is the correct formula for the function? y = –x – 1 y = x

You forgot to mention the graph.
So, I make the graph of both given functions and you will compare your graph with them.

First, y= -x-1
put y=0 you get point (-1,0) called x-intercept
put x=0 you get point (0,-1) called y-intercept
join both the points, you will get the graph
Graph is attached in the picture.

Second, y= x+1
put y=0 you get point (-1,0) called x-intercept
put x=0 you get point (0,1) called y-intercept
join both the points, you will get the graph
