-5- -5=0 which leads to slope of zero. (0, -5) is the y-intercept so it is Y= -5
30,12,6,6,36 there you go
T=tickets sold
alrighty, so we need 400 and we have 75
what we need must be greater than or equal to the cost
cost=400
what we need=what we have+what we will earn
what we have=75
what we will earn=cost per ticket times number of tickets=4 times t=4t
so
75+4t≥400 would be a possible inequality
