The slope intercept form of the equation y - 9 = - (x+2) is y = -x + 7.
When any equation is represented in the y = m x +c form, it is called the slope intercept form of the equation.
Here m is slope and c is constant.
The given equation of line is,
y - 9 = - (x + 2)
To convert, the equation is slope intercept form,
Simplify the equation,
y - 9 = -x - 2
y = -x -2 + 9
y = -x + 7.
The required slope intercept form of the equation is y = -x + 7.

Answer:
y = - 3
Step-by-step explanation:
Locate x = 2 on the x- axis, then go down vertically until the line is met.
Then read the corresponding y- coordinate at this point.
When x = 2 the value of the function is y = - 3
Answer:
-3
Step-by-step explanation:
We are given that a graph.
We have to find the value of the function at x=2.
To find the value of function at x=2 we will find the value of y corresponding to x=2 by drawing a vertical line x=2
The given graph is the graph of a line.
We can see that when we draw a vertical line x=2 and parallel to y- axis.
Then, the vertical line x=2 cut the given line at pint (2,-3).
Therefore, the intersection point of line x=2 and the given line is (2,-3).
The value of y corresponding to x=2 is -3.
We know that
Therefore, the value of the given function at x=2 is -3.
Hence, the value of the function at x=2 is -3.
