A useful first step is to swap the variables: put y where x is, and put x where y (or f(x)) is. The rest follows from there.
Answer:
Step-by-step explanation:
y=mx+b
so inset the first point into the equation
-3 for x and 7 for y.
7=m(-3)+b
y=mx+b
1 for x and -1 for y
-1=m(1)+b
now put them together and solve for m and b.
-1=m+b
7=-3m+b
--------------------
-1-b=m
7=-3m+b
inset m into the equation
7=-3(-1-b)+b
7=3+3b+b
4=4b
b=1
--------------
insert b back in for -1=m+b
-1=m+1
m=-2
---------------------------------------
Now insert it back into y=mx+b
y=(-2)x+1
so this line contains those points that were given
Hope this helps :)
Answer: 100
set up equation: GHE+EHI=GHI
(x+38)+(x+104)=134
calculate
you get x= -4
put -4 into EHI
(-4)+104= 100
