Answer:
y = 95
Step-by-step explanation:
x + 120 = 180
25 + x + y = 180
flipping the first equation 180 - 120 = 60 so x is 60.
so plug in 60 into the second equation
25 + 60 + y =180 --> 85 + y =180 flip equation 180 - 85 = 95
so y is 95
Y=mx+b
0=-1/2x-2
2=-1/2x
X= -4
We will set y=0 so we can know the value of x when line crosses the x axis
