If your trying to get Y=mx + b the answer would be 1. Y= x+4 2. Y= -1/3x + 4/3
Answer:
x - intercept = 8
y - intercept = 4
Step-by-step explanation:
In order to to find x- intercept, plug y = 0, in the given equation of line.
In order to to find y- intercept, plug x = 0, in the given equation of line.
![\frac{1} {2} x+y = 4\\\\\frac{1} {2} \times 0+y = 4..(plug \: x = 0)\\0+y = 4\\y = 4\\\huge \purple {\boxed {\therefore y-intercept = 4}}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%20%7B2%7D%20x%2By%20%3D%204%5C%5C%5C%5C%3C%2Fp%3E%3Cp%3E%5Cfrac%7B1%7D%20%7B2%7D%20%5Ctimes%200%2By%20%3D%204..%28plug%20%5C%3A%20x%20%3D%200%29%5C%5C%3C%2Fp%3E%3Cp%3E0%2By%20%3D%204%5C%5C%3C%2Fp%3E%3Cp%3Ey%20%3D%204%5C%5C%3C%2Fp%3E%3Cp%3E%5Chuge%20%5Cpurple%20%7B%5Cboxed%20%7B%5Ctherefore%20y-intercept%20%3D%204%7D%7D%20)
So remember you can add like terms
10x-8xy-3xy
you can add the -8xy and -3xy but not the 10x
-8xy+-3xy=-11xy
the equaton is
10x-11xy
