These are the points graphed:
Are they equal? Yes.
Answer:
![y=-\frac{9}{7}x-2](https://tex.z-dn.net/?f=y%3D-%5Cfrac%7B9%7D%7B7%7Dx-2)
Step-by-step explanation:
Here, we have to convert the equation to slope-intercept form so we can find the perpendicular slope:
![7x-9y=-5](https://tex.z-dn.net/?f=7x-9y%3D-5)
![-9y=-5-7x](https://tex.z-dn.net/?f=-9y%3D-5-7x)
![y=-\frac{5}{9}+\frac{7}{9}x](https://tex.z-dn.net/?f=y%3D-%5Cfrac%7B5%7D%7B9%7D%2B%5Cfrac%7B7%7D%7B9%7Dx)
![y=\frac{7}{9}x-\frac{5}{9}](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B7%7D%7B9%7Dx-%5Cfrac%7B5%7D%7B9%7D)
Since our slope is
, then that means the slope perpendicular to it is
.
Now we find our new y-intercept so that the line will pass through the point (-7,7):
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
![y=-\frac{9}{7}+b](https://tex.z-dn.net/?f=y%3D-%5Cfrac%7B9%7D%7B7%7D%2Bb)
![7=-\frac{9}{7}(-7)+b](https://tex.z-dn.net/?f=7%3D-%5Cfrac%7B9%7D%7B7%7D%28-7%29%2Bb)
![7=9+b](https://tex.z-dn.net/?f=7%3D9%2Bb)
![-2=b](https://tex.z-dn.net/?f=-2%3Db)
Therefore, the equation of the new line is ![y=-\frac{9}{7}x-2](https://tex.z-dn.net/?f=y%3D-%5Cfrac%7B9%7D%7B7%7Dx-2)
Answer:
60 +(n x 15) = total cost
Step-by-step explanation:
The answer is d) that is the answer.
That would be 25 because it is 5*5.
