Answer:
P'(7 , -11)
Step-by-step explanation:
what this tells us
(x,y) → ( x+3, y−2)
Is that the value of x of the new point is going to take (x + 3) with respect to the value of x of the other point.
Is that the value of y of the new point is going to take (y - 2) with respect to the value of y of the other point.
P (4,−9)
x = 4
y = -9
P'( x+3, y−2)
x + 3 =
4 + 3 = 7
y - 2 =
-9 - 2 = -11
P'(7 , -11)
When given a value of the variable, we replace each instance of the variable in the problem with that number. In this case, the expression becomes:

After this, we merely need to simplify the answer.


Simplifying 12/2 gives us the answer 6.
Answer:
y = -2x + 16
Step-by-step explanation:
So first you plug in the values you know into the slop int. form, equation, in which it is y = mx +b. When you plug in the slope value then you will get the equation of y = -2x +b, in which then you have to solve for the b value.
In order to solve for the b value, you then plug in the x and y values of the coordinate that is given so what you would do is this: 6 = -2(5) +b
6 = -10 +b
16 = b
So then you find out b is 16 in which you just plug back into the equation. So finally you write the equation, y = -2x+16.
