Answer:
y =(-3/2)x
Step-by-step explanation:
(0,0) ; (2 , -3)
Slope = 

Equation: y - y1 =m(x-x1)
y - 0 = 

Parameterize the part of the surface we care about, denoted
, by

with
and
.
Then

The area is given by the surface integral


Answer:

Step-by-step explanation:
Mark any two point on the line
(-1 , 0) & (-3 , -1)
Slope = 
![= \frac{-1-0}{-3-[-1]}\\\\= \frac{-1}{-3+1}\\\\= \frac{-1}{-2}\\\\= \frac{1}{2}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B-1-0%7D%7B-3-%5B-1%5D%7D%5C%5C%5C%5C%3D%20%5Cfrac%7B-1%7D%7B-3%2B1%7D%5C%5C%5C%5C%3D%20%5Cfrac%7B-1%7D%7B-2%7D%5C%5C%5C%5C%3D%20%5Cfrac%7B1%7D%7B2%7D)
m = 1/2 ; (-1 , 0)
Equation: 
![y - 0 = \frac{1}{2}(x - [-1])\\\\y = \frac{1}{2}(x + 1)\\\\y = \frac{1}{2}x + \frac{1}{2}](https://tex.z-dn.net/?f=y%20-%200%20%3D%20%5Cfrac%7B1%7D%7B2%7D%28x%20-%20%5B-1%5D%29%5C%5C%5C%5Cy%20%3D%20%5Cfrac%7B1%7D%7B2%7D%28x%20%2B%201%29%5C%5C%5C%5Cy%20%3D%20%5Cfrac%7B1%7D%7B2%7Dx%20%2B%20%5Cfrac%7B1%7D%7B2%7D)
Maybe 240 I just multiplied 15 and 16 because 12 times 4 is 16
Answer:
The new side lengths will be 24 inches and 40 inches
Step-by-step explanation:
Here, given the width and length of a rectangle and we want to create a scaled copy using a scale factor of 4, we want to know the new side lengths
What we simply want to do here is to scale up or dilate the side lengths of the rectangle using a scale factor of 4
Hence, the new side lengths will be (4 * 6) inches and (10 * 4) inches
The new side lengths will be 24 inches and 40 inches
