Answer:
y = -x + 2
Step-by-step explanation:
The slope intercept form equation of this line can be written like this :
y = my + p ; where m is the slope and p is the y intercept.
![m = \frac{-1-4}{3-(-2)} = \frac{-5}{5} =-1](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B-1-4%7D%7B3-%28-2%29%7D%20%3D%20%5Cfrac%7B-5%7D%7B5%7D%20%3D-1)
then the equation becomes y = -x + p
(-2,4) is a point of the line means 4 = -(-2) + p
then p = 4 - 2 = 2
finally, y = -x + 2
Answer:
M/N=5/8 or 62.5%
Step-by-step explanation:
when turning the word problem to equation...
![\frac{x}{y} \frac{80}{100}*M=\frac{50}{100}N\\\\ \frac{80M}{100}=\frac{50N}{100}\\ then you should criss-cross\\\100(80M)=100(50N) then you divide both sides by 100)\\80M=50N\\\\\frac{80M}{80}=\frac{50N}{80}\\ M=\frac{50}{80}=\frac{5N}{8}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7By%7D%20%5Cfrac%7B80%7D%7B100%7D%2AM%3D%5Cfrac%7B50%7D%7B100%7DN%5C%5C%5C%5C%20%5Cfrac%7B80M%7D%7B100%7D%3D%5Cfrac%7B50N%7D%7B100%7D%5C%5C%20%20then%20you%20should%20criss-cross%5C%5C%5C100%2880M%29%3D100%2850N%29%20then%20you%20divide%20both%20sides%20by%20100%29%5C%5C80M%3D50N%5C%5C%5C%5C%5Cfrac%7B80M%7D%7B80%7D%3D%5Cfrac%7B50N%7D%7B80%7D%5C%5C%20%20M%3D%5Cfrac%7B50%7D%7B80%7D%3D%5Cfrac%7B5N%7D%7B8%7D)
since you have the value of M in terms of N you should substitute M by 5N/8.
if you want it as a percent just multiply 5/8 by 100%.
![BY PERCENT=\frac{5}{8}*100%=\frac{500}{8}=62.5%](https://tex.z-dn.net/?f=BY%20PERCENT%3D%5Cfrac%7B5%7D%7B8%7D%2A100%25%3D%5Cfrac%7B500%7D%7B8%7D%3D62.5%25)
=62.5%
