Answer: Option A.
Step-by-step explanation:
Based on the information given in the problem, you can draw the figure shown attached.
The area of rectangle can be calculated with the following formula:
Where <em>l</em> is the length and <em>w</em> is the width.
As you can see in the figure:
- The width is:
-The length is:
Therefore, you must multiply both expressions to obtain the area:
Add like terms:
Then, the function that represents the area of the cake is:
The two points (-3,5) and (6,-2) are on this line. Using the slope formula, we get
m = (y2-y1)/(x2-x1)
m = (-2-5)/(6-(-3))
m = (-2-5)/(6+3)
m = -7/9
-------------------------------
Now use this slope value, and the point (x,y) = (-3,5), to find the y intercept b
y = mx+b
5 = (-7/9)(-3)+b
5 = 7/3+b
5-7/3 = 7/3+b-7/3
8/3 = b
b = 8/3
-------------------------------
We go from y = mx+b to y = (-7/9)x + 8/3
So the linear function is
which is the final answer
-------------------------------
Check:
Plug in x = -3
So that checks out.
----------
Plug in x = 6
and that checks out at as well. The answer has been fully confirmed.
