No it is false because when you solve the equation 9 is not equal to 1
C is the only one that shows all
<h2>Answer </h2>
negative
<h2>Explanation </h2>
Let's find the slope of our line using the slope formula:
![m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_%7B2%7D-y_%7B1%7D%7D%7Bx_%7B2%7D-x_%7B1%7D%7D)
where
is the slope of the line
are the coordinates of the first point on the line
are the coordinates of the second point
From the graph we can get the points (-2, 1) and (2, -1), so
,
,
, and
. Let's replace the values in our formula to find
:
![m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_%7B2%7D-y_%7B1%7D%7D%7Bx_%7B2%7D-x_%7B1%7D%7D)
![m=\frac{-1-1}{2-(-2)}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B-1-1%7D%7B2-%28-2%29%7D)
![m=\frac{-2}{2+2}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B-2%7D%7B2%2B2%7D)
![m=\frac{-2}{4}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B-2%7D%7B4%7D)
![m=-\frac{2}{4}](https://tex.z-dn.net/?f=m%3D-%5Cfrac%7B2%7D%7B4%7D)
![m=-\frac{1}{2}](https://tex.z-dn.net/?f=m%3D-%5Cfrac%7B1%7D%7B2%7D)
The slope of the graph of the linear function is
; since
is a negative number, the slope of the graph is negative.
![\displaystyle\int_{x=0}^{x=1}\int_{y=1}^{y=x}\cos y^2\,\mathrm dy\,\mathrm dx](https://tex.z-dn.net/?f=%5Cdisplaystyle%5Cint_%7Bx%3D0%7D%5E%7Bx%3D1%7D%5Cint_%7By%3D1%7D%5E%7By%3Dx%7D%5Ccos%20y%5E2%5C%2C%5Cmathrm%20dy%5C%2C%5Cmathrm%20dx)
Change the order of integration. The region over which you're integrating can be equivalently described by the set of points in the plane,
.
Then the integral becomes
![\displaystyle\int_{y=0}^{y=1}\int_{x=0}^{x=y}\cos y^2\,\mathrm dx\,\mathrm dy=\int_{y=0}^{y=1}y\cos y^2\,\mathrm dy](https://tex.z-dn.net/?f=%5Cdisplaystyle%5Cint_%7By%3D0%7D%5E%7By%3D1%7D%5Cint_%7Bx%3D0%7D%5E%7Bx%3Dy%7D%5Ccos%20y%5E2%5C%2C%5Cmathrm%20dx%5C%2C%5Cmathrm%20dy%3D%5Cint_%7By%3D0%7D%5E%7By%3D1%7Dy%5Ccos%20y%5E2%5C%2C%5Cmathrm%20dy)
Substitute
,
:
![\displaystyle\frac12\int_{z=0}^{z=1}\cos z\,\mathrm dz=\frac12\sin1](https://tex.z-dn.net/?f=%5Cdisplaystyle%5Cfrac12%5Cint_%7Bz%3D0%7D%5E%7Bz%3D1%7D%5Ccos%20z%5C%2C%5Cmathrm%20dz%3D%5Cfrac12%5Csin1)
