Should be B.
as x represents the week number you simply plug in 8 for X so,
y=-1.2(8)+23.5
y=13.9 that is just 14 then
Answer:
one, different, one
Step-by-step explanation:
The equations:
y = x + 1
y = 2x + 2
Have different slopes, bc the slopes are the numbers in front of the x. So the first equation has slope of 1 (just x means 1x ) and the second equation has a slope of 2. So they are both lines and they are not parallel (with the same slope, which means they would not intersect) also not the same line (which would mean one line laying exactly on top of the other which is infinite number of solutions)
These are two different lines and they will cross at one point.
