The area of this rectangle is 18 square units. What is the unit of measurement?
Answer:
The slope is 2.
Step-by-step explanation:
Use the slope formula:
m = y2 - y1 / x2 - x1
Plug in the numbers from the ordered pairs:
m = 3 - 1 / 1 - 0
m = 2/1
Simplify:
m = 2
Centre is at the middle or the midpoint of the diameter.
And the formula of midpoint is

For the given question, x1=-4, y1=2, x2=2, y2=-8
So we will get

And that's the required centre .

Answer:

Step-by-step explanation:
We know that f(-2)=7
x+4 = -2 <=> x = -6
so f(-6+4) = f(-2)=7
then the corresponding point is (-6,7)
