starting value is if x=1, then y=what
and we jjust want to find the bigggest y
(x,y)
so for the first one
A. (1,1) so when x=1 then y=1,
B. y=-7x-8
we can imediately see that this is small since everything is negative
y=-7-8
y=-15
C.5x+15y=-30
subsitute 1 for x
5(1)+15y=-30
5+15y=-30
subtract 5
15y=-35
divie 15
y=-2 and 1/3
so we have
A. y=1
B. y=-15
C. y=-2 and 1/3
1 is biggerst
answer is A
